Schlieren Apparatus (Product Code: SLE/EA/02) is an optical flow-visualisation system used to make density gradients in air visible, so that students can see supersonic flow patterns, shockwaves and expansions around models in aerodynamics and gas dynamics laboratories. It displays density changes as variations in illumination intensity and includes digital imaging equipment to record what students see. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Schlieren Apparatus Used For?

Air is invisible, but where its density changes, light passing through it is bent very slightly. A schlieren system turns that bending into brighter and darker regions on the image, so a shockwave in front of a model appears as a sharp line and an expansion fan appears as a graded band. This lets students see the structure of supersonic flow instead of only inferring it from pressure readings.

Intermittent supersonic tunnels run for short bursts, which is why the included digital imaging equipment matters: each run can be captured and studied afterwards. Students measure shock angles from the saved images and check them against oblique-shock theory for the model and Mach number used. Keep the mirrors and lenses clean and covered when not in use, and align the optics before every session.

What to Specify When Ordering

• The wind tunnel or test section the apparatus will be used with, including the size of the viewing window.
• How you intend to store and view recorded images (for example on a departmental PC); ask us about the imaging equipment supplied.

Resistance Substitution Box (Product Code: SLE/EAM/07) is a robust resistance box for the physics lab that lets students build any value from 1 to 12,221 Ω by linking its internal resistors in series through 4 mm sockets. A printed connection diagram on the panel shows exactly which sockets to join, so the box works equally well as a known resistor, a variable load or a stand-in for an unknown component. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

Typical Use

The name describes its classic job: the substitution method. Students measure the current through an unknown resistor, swap the box into its place and adjust the selected value until the meter shows the same reading; the box setting then equals the unknown resistance. The same box serves as the known arm when balancing Wheatstone bridge experiments, as a stepped load for plotting current against voltage, and as a series resistor when a lamp or LED needs its current limiting.

Because every resistance is made by joining sockets rather than turning a dial, the circuit on the panel matches the circuit diagram in the notebook, which helps students connect the idea of resistors adding in series with a real measurement. Keep an eye on the 2 W rating: at low resistance settings, a higher supply voltage can push the dissipated power up quickly, so check the expected current before switching on and start at a modest voltage.

Manufacturer

This box is built by Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, Haryana, and is a registered MSME manufacturer (Udyam UDYAM-HR-01-0003714); export consignments are shipped under Importer-Exporter Code AAECJ8618A issued by the DGFT. Visit the company profile to learn more about ScienceLab.

Related Electricity and Magnetism Equipment

To wire the box into a measuring circuit, buyers commonly add:

• Stackable Leads — 4 mm leads for linking the sockets and connecting the box to the circuit.
• Digital Ammeter — provides the matching current reading at the heart of the substitution method.
• Digital Voltmeter — measures the potential difference across the selected resistance.
• Wheatstone Bridge Four Gap — the box can act as the known resistance when balancing the bridge.
• Decade Resistance Box — an alternative style of resistance box for labs comparing formats.

Explore more circuit apparatus in the Electricity and Magnetism category.

Frequently Asked Questions

What resistance values can I set?
Any value from 1 to 12,221 Ω that the internal resistors can make when connected in series, chosen by linking the 4 mm sockets as shown on the panel diagram.

How much power can the box handle?
It is rated at 2 W. Work out the expected power before connecting, especially when a low resistance is selected with a higher supply voltage.

What leads does it take?
Connections are made through 4 mm sockets, so standard 4 mm plug leads are used both to link resistors and to connect the box into a circuit.

What is the tolerance of the resistors?
The tolerance is not listed on this page. If your practical needs a specific tolerance, please check with us through the contact page before ordering.

Is a calibration certificate available?
Certificate availability depends on the order, so please discuss it with us when you request a quote.

What should our purchase enquiry include?
Give the quantity, the delivery location and any tender or vendor-registration paperwork you need; we supply schools, colleges and distributors in India and international markets.

Flow Visualisation Wind Tunnel (Product Code: SLE/EA/03) is a vertical, suction-type smoke wind tunnel used to show how air flows around differently shaped models during demonstrations and student investigations in aerodynamics and fluid mechanics laboratories. Its distinguishing feature is a smoke comb below the lit, transparent working section, fed by a generator that vaporises food-grade oil, with air flowing vertically upwards. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Flow Visualisation Wind Tunnel Used For?

Smoke released from the comb forms thin, parallel filaments that rise through the working section and bend around whatever model is fixed there. A class can watch the streamlines stay attached to a streamlined shape, break away behind a flat plate or cylinder, and roll up into a wake. Moving the comb from side to side lets students trace the flow over the top, middle or edge of a model, and changing fan speed shows how the pattern alters as velocity rises.

The removable front wall makes swapping models quick between demonstrations, and the lamps on both sides make the smoke easy to see, even for a group standing back from the tunnel. Dim the room lights for the clearest view, keep the smoke generator topped up with the correct oil, and wheel the tunnel to a store area on its castors after use.

What to Specify When Ordering

• Which optional models you want for the working section.
• Supply of smoke oil for the generator; ask us about the correct grade and quantity.
• Your mains supply for the fan, lamps and smoke generator, which is not stated in the listing.
• Number of tunnels for lecture rooms and student labs.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM behind the Flow Visualisation Wind Tunnel. The tunnel is manufactured at the company's own licensed factory at 449, HSIIDC Industrial Area, Saha, Ambala, Haryana, India, and dispatched directly from there to customers.

Because the maker handles every enquiry itself, schools of engineering, science centres, dealers and importers can order extra models, spares and repeat units from the same source — ask us for anything you need. Find more on the company profile.

Browse all Aerodynamics Lab Equipment.

Frequently Asked Questions

How does the Flow Visualisation Wind Tunnel produce smoke?
The Flow Visualisation Wind Tunnel uses a smoke generator that vaporises food-grade oil. The smoke, listed as non-toxic, is fed to a comb below the working section, where it forms visible filaments that follow the upward air flow around the model.

Which way does air flow in the Flow Visualisation Wind Tunnel?
Air flows vertically upwards in the Flow Visualisation Wind Tunnel. It is a suction-type tunnel: a variable-speed fan on top draws air through a filter and the working section, which helps give a uniform flow for clear smoke lines.

Are models included with the Flow Visualisation Wind Tunnel?
Models for the Flow Visualisation Wind Tunnel are listed as optional. They attach to the back of the working section once the transparent front wall is removed. Tell us which shapes you want so they can be added to your quotation.

Can the Flow Visualisation Wind Tunnel be moved between rooms?
Yes. The Flow Visualisation Wind Tunnel stands on a metal frame fitted with castors, and the fan-speed control unit is mounted on the same frame, so the whole tunnel can be wheeled between a lecture room and a laboratory.

Faraday's Law Apparatus (Product Code: SLE/EAM/08) is an electromagnetic induction apparatus used to show and measure the pulse of electricity a falling magnet induces in a coil, in school and college physics labs. A small cylindrical magnet, supplied with it, drops down an acrylic tube through a movable coil, and twin coils of 150 and 300 turns let students compare results. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, as part of its electromagnetic induction kit range.

Specifications

What Is the Faraday's Law Apparatus Used For?

A first run is purely qualitative: drop the magnet and watch the oscilloscope trace rise and then swing the other way as the magnet enters and leaves the coil, a direct picture of Lenz's law. Switching between the 150-turn and 300-turn coils then shows how the size of the induced pulse depends on the number of turns, while turning the magnet over reverses the trace. A PC-based oscilloscope makes this especially easy because each single-shot event can be captured, stored and compared on screen.

For senior students the apparatus becomes a quantitative investigation of Faraday's law. Sliding the coil to a different position on the tube changes how far the magnet falls before reaching it, and therefore its speed; students work out that speed from the equations of motion and plot pulse amplitude against it. It is compact physics lab equipment in India's senior classrooms that ties induction to mechanics in one practical. Place a soft pad at the bottom of the tube so the magnet is not chipped by repeated drops.

OEM Manufacturer

Jain Scientific Equipments Private Limited, which trades as ScienceLab, is the OEM (original equipment manufacturer) of the Faraday's Law Apparatus and makes it at its own licensed factory at Saha, Ambala, Haryana, India. The apparatus is built and assembled by the company itself rather than sourced from a trader, and it goes factory-direct to schools, colleges, dealers and importers. If you later need a replacement magnet or coil, ask us: spares and repeat orders are handled by the manufacturer. Read more on the company profile.

Frequently Asked Questions

What comes with the Faraday's Law Apparatus?
The Faraday's Law Apparatus comes with the acrylic guide tube and its movable coil arrangement, twin coils of 150 and 300 turns, a small cylindrical magnet and full instructions. An oscilloscope is needed to display the pulse but is ordered as a separate item.

Does the Faraday's Law Apparatus need an oscilloscope?
Yes. The Faraday's Law Apparatus produces a brief pulse of electricity each time the magnet falls through the coil, and an oscilloscope is used to monitor that pulse and measure its amplitude. PC-based oscilloscopes are particularly suited because they capture single events.

Why does the Faraday's Law Apparatus have two coils?
The twin coils of 150 and 300 turns let students compare the induced pulse for two different numbers of turns on the Faraday's Law Apparatus, adding a second variable alongside magnet speed and showing how the induced voltage depends on the turns.

How do students change the magnet speed?
On the Faraday's Law Apparatus the coil is moved along the acrylic tube, which changes how far the magnet falls before reaching it. Senior students calculate the speed at the coil from the equations of motion and relate it to the measured pulse amplitude.

Who manufactures the Faraday's Law Apparatus?
The Faraday's Law Apparatus is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as the OEM, at its own licensed factory at Saha, Ambala, Haryana, India. Quotations, repeat orders and questions about a spare magnet come straight from the manufacturer through our contact page.

What should a quotation request include?

Digital Ammeter (Product Code: SLE/EAM/09) measures direct current from 0 to ±10 A and shows it to 0.01 A, so one meter covers both small lamp circuits and the heavy currents used in electromagnetism demonstrations. Running from a 9 V PP3 battery, it needs no mains connection on the bench, which makes it a practical addition to the physics lab instruments used in school and college practicals. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

Typical Use

The meter is wired in series with the component being studied, and its very low input impedance means it adds almost nothing to the resistance of the circuit, so the current it shows is the current that would flow without it. Together with a voltmeter it forms the familiar ammeter-voltmeter pair for Ohm's law, resistivity and power experiments, and the bipolar range shows a minus sign rather than a damaged movement if a student connects it the wrong way round.

The upper end of the range is where this meter earns its place. Demonstrations such as the magnetic field around a vertical wire or the force on a current-carrying conductor need several amperes, well beyond many general-purpose classroom meters, and this ammeter lets the class read the actual current rather than guess it. One rule is worth repeating before every practical: an ammeter must never be connected directly across a power supply or cell, because its low impedance would effectively short-circuit the source.

Manufacturer

Jain Scientific Equipments Private Limited, operating under the ScienceLab trade name in Ambala, Haryana, produces this ammeter as part of its range of meters and circuit apparatus for schools, colleges and technical institutes. Company background is available on the ScienceLab profile.

Related Electricity and Magnetism Equipment

The following items are used in the same circuits and demonstrations as this ammeter:

• Digital Voltmeter — the partner meter for potential difference in the same practical.
• Magnetic Field Unit Vertical Wire — runs at 5–8 A, a current this meter can monitor.
• Force on a Conductor Apparatus — takes currents of up to 8 A, within the meter's range.
• Lost Volts — internal-resistance apparatus that needs an ammeter and a voltmeter.
• Precision Switched Power Supply — a regulated, high-current DC source for these circuits.

More meters and apparatus are listed under Electricity and Magnetism.

Frequently Asked Questions

What current range does it cover?
0 to ±10 A DC, displayed in steps of 0.01 A with an accuracy of ±2%.

Is it sensitive enough for very small currents?
It reads in hundredths of an ampere, which suits lamps, motors and electromagnet circuits. For milliamp-level work such as LED characteristics, ask us to suggest a more sensitive meter.

How is it powered?
By a 9 V PP3 battery, so it can be used on any bench without a mains socket.

Can it measure AC current?
The published range is DC only. If you need AC current measurement, contact us before ordering.

How should students connect it?
Always in series with the component. Connecting it across a supply creates a near short circuit because of its very low input impedance of about 0.01 Ω.

Can you provide a calibration certificate or warranty details?
Both are confirmed per order. Please raise them through our contact page when requesting a quote.

Magnetic Field Unit Vertical Wire (Product Code: SLE/EAM/10) is a clear acrylic base with a straight conductor passing vertically through it, used to reveal the circular magnetic field around a current-carrying wire with plotting compasses or iron filings. It belongs to a small electromagnetic kit for schools made up of three field units, and its transparent base works on the bench or on an overhead projector for whole-class viewing. The unit is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

Typical Use

With the wire connected to a high-current DC supply, students sprinkle a thin layer of iron filings on the acrylic base and tap it gently; the filings settle into concentric rings centred on the wire. Replacing the filings with a ring of plotting compasses shows the direction of the field, and reversing the supply leads makes every needle swing round, which is the ideal moment to introduce the right-hand grip rule. Placed on an overhead projector, the same pattern is thrown onto the screen so the whole room can follow it.

Because the unit needs 5 to 8 A to give a clear pattern, switch the current on only while observing and off again straight after, so the wire and supply stay cool. As a magnetism experiment it pairs naturally with the solenoid and twin-coil versions in the same series, letting students compare the field of a single straight wire with that of a coil. Brush filings onto a sheet of paper afterwards and keep them well away from the sockets.

Manufacturer

This field unit comes from Jain Scientific Equipments Private Limited, which trades as ScienceLab and manufactures physics apparatus in Ambala, Haryana. Institutional and tender buyers who need vendor registration details can quote GSTIN 06AAECJ8618A1ZT and LEI 3358004HRD1JIVXKYX49. The company profile has further information.

Related Electricity and Magnetism Equipment

A complete field-pattern demonstration usually calls for the following:

• Precision Switched Power Supply — regulated DC rated up to 8 A, matching the unit's supply requirement.
• Digital Ammeter — its 10 A range lets students record the current through the wire.
• Compass Plotting (Clear) — small plotting compasses for tracing the field direction around the wire.
• Plotting Compass, Single Glass Face — an alternative compass style for the same task.
• Stackable Leads — 4 mm leads for connecting the unit's sockets to the supply.

See the complete Electricity and Magnetism range for the other field units and accessories.

Two Channel Recorder (Product Code: SLE/EA/04) is a two-pen chart recorder used to draw a permanent paper trace of electrical signals during laboratory experiments, and it is listed to work with the Flight Demonstration Wind Tunnel. Engineering lab staff use it for its 200 mm chart, a 1 mV to 50 V input range, 16 chart speeds and long-life fibre-tip pens that stand up to student use. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the Two Channel Recorder Used For?

A chart recorder moves paper at a set speed while a pen follows the input voltage, so a changing quantity is drawn as a line against time. With two pens, students can plot two signals on one chart and see directly how one responds to the other, which is ideal for transient experiments such as the motion demonstrations on a wind tunnel model. The paper record can be annotated, measured with a ruler and stapled into the lab report.

Pick a fast mm/sec speed to spread out quick events and a slow mm/min speed for long runs. Set each channel's range so the trace uses most of the 200 mm width without hitting the edge. The electric pen-lift on each channel lets you raise a pen between runs to avoid stray marks, and capping the pens after the session keeps the fibre tips from drying out.

What to Specify When Ordering

• 1-channel or 2-channel version.
• The signals you will record, so they can be checked against the 1 mV – 50 V range.
• Whether it will be used with the Flight Demonstration Wind Tunnel or with other apparatus.
• Spare pens and chart paper for the term; ask us what can be quoted.

Supplier

Jain Scientific Equipments Private Limited, under its ScienceLab brand, supplies the Two Channel Recorder to aeronautical and mechanical engineering departments, polytechnics, dealers and importers in India and international markets. The recorder can be quoted together with the wind tunnel and other aerodynamics equipment in one order.

For company background, see the ScienceLab profile.

• Oscilloscope Dual Trace — for viewing fast two-channel signals on screen instead of paper.
• Advanced Digital Multimeter — checks signal levels before setting the recorder range.

See the full Aerodynamics Lab Equipment category.

Frequently Asked Questions

What is the input range of the Two Channel Recorder?
The Two Channel Recorder covers an input range of 1 mV to 50 V, which lets it trace both small sensor signals and larger voltages. Choose the range on each channel so the trace fills the 200 mm chart without running off the edge.

How many chart speeds does the Two Channel Recorder have?
The Two Channel Recorder offers 16 different chart speeds from 0.1 to 20, selectable in mm/sec or mm/min. Fast speeds spread out quick transients, while slow speeds suit long, gradual runs.

Is the Two Channel Recorder available in a single-channel version?
Yes. The Two Channel Recorder is listed in 1-channel and 2-channel versions. Each channel has its own electric pen-lift, so on the two-channel model either pen can be raised independently between runs.

Which apparatus does the Two Channel Recorder work with?
The Two Channel Recorder is listed to work with the Flight Demonstration Wind Tunnel. It can also record other voltage signals within its 1 mV to 50 V range; confirm your signal source with us through the contact page.

Flight Demonstration Wind Tunnel (Product Code: SLE/EA/05) is a teaching wind tunnel with a free-moving model aircraft used to demonstrate the basic principles of flight — aerofoil lift, stall, longitudinal stability and transient motion — in aeronautical and mechanical engineering classrooms. The model can move vertically and pitch about its quarter-chord point independently, while an electronic display shows air speed, attitude, altitude, pressure and lift. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Flight Demonstration Wind Tunnel Used For?

Unlike a tunnel where the model is held rigidly on a balance, here the aircraft is free to rise and pitch, so students see it behave the way a real aeroplane does. As air speed increases the model lifts off, settles into level flight and cruise, and comes back down for a landing when speed is reduced. When the wing reaches too steep an angle, the tufts on the wing flutter and reverse as the flow separates, giving a clear visual of stall that matches the drop in lift on the display.

Shifting the adjustable centre of gravity forward or aft is a direct way to teach longitudinal stability: students watch the model damp out a disturbance in one setting and oscillate or diverge in another. For transient-motion work, the Two Channel Recorder can be added to put the response on paper. The illuminated working section keeps the model visible to a whole class during lectures.

What to Specify When Ordering

• Whether you want the Two Channel Recorder quoted with the tunnel for paper records.
• Your mains supply for the fan, display and lighting (not stated in the listing).
• Room layout and viewing arrangement for lecture demonstrations.
• Number of units required.

OEM Manufacturer

The Flight Demonstration Wind Tunnel is manufactured by Jain Scientific Equipments Private Limited, which operates under the ScienceLab name, as the original equipment manufacturer. It is produced at the company's licensed factory in Saha, Ambala, Haryana, India, and supplied from the factory to aviation training institutes, engineering colleges, dealers and importers.

Dealing with the manufacturer directly means one point of contact for technical questions, replacement parts such as models or tufts, and repeat orders — just ask us. More about the company is on the profile page.

Frequently Asked Questions

What does the Flight Demonstration Wind Tunnel demonstrate?
The Flight Demonstration Wind Tunnel demonstrates aerofoil lift, stall, longitudinal stability and transient motion. Its model aircraft simulates take-off, level flight, cruise and landing, so students connect textbook theory with visible aircraft behaviour.

How does the model move in the Flight Demonstration Wind Tunnel?
In the Flight Demonstration Wind Tunnel, the model aircraft can move vertically and pitch about its quarter-chord point, each independently. This freedom lets it respond to air speed and centre-of-gravity changes much as a real aircraft would.

What readings does the Flight Demonstration Wind Tunnel display?
The Flight Demonstration Wind Tunnel includes an electronic display of air speed, attitude, altitude, pressure and lift, so the class can link what they see the model doing with measured values at the same moment.

How is stall shown on the Flight Demonstration Wind Tunnel?
On the Flight Demonstration Wind Tunnel, tufts attached to the wing clearly show flow separation and stall. As the angle rises past the stall point, the tufts become disturbed and reverse, while the displayed lift falls.

Who manufactures the Flight Demonstration Wind Tunnel?
The Flight Demonstration Wind Tunnel is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory in Ambala, Haryana, India, and supplied factory-direct to institutions in India and international markets.

Can a chart recorder be used with the Flight Demonstration Wind Tunnel?
