What Is the Extended Surface Heat Transfer Apparatus Used For?
Fins on engine cylinders and heat sinks on electronics work on the same principle as this bar. Students connect the heater and thermocouples to the base unit, let the bar reach a steady state and record the temperature at each point, then plot the temperature profile along its length and compare it with fin theory, including fin efficiency.
Because the matt black coating gives a known emissivity, the radiation share of the heat loss can be calculated and separated from natural convection. Students then use their first results to predict temperatures and heat flow for a new condition and test the prediction, which makes it dependable lab equipment for college heat transfer courses in India.
What to Specify When Ordering
- Whether you need the Heat Transfer Experiments Base Unit, since the heater and thermocouples plug into its sockets.
- Which other experiments from the same base-unit range you want to add.

Frequently Asked Questions
What is an extended surface?
An extended surface, or fin, is a part that projects from a hot body to increase its heat loss. The Extended Surface Heat Transfer apparatus models one as a thin solid bar heated at one end, losing heat along its length.
Why is the bar coated matt black?
The matt black coating on the Extended Surface Heat Transfer bar gives a consistent and predictable emissivity value, so students can calculate the heat lost by radiation with confidence and separate it from the heat lost by natural convection.
How are temperatures measured along the bar?
Thermocouples on the Extended Surface Heat Transfer apparatus measure the temperature along the surface of the bar at equally spaced intervals, which lets students plot a clear temperature profile from the heated end to the tip.
Does it need the Heat Transfer Experiments Base Unit?
Yes. The heater and thermocouples of the Extended Surface Heat Transfer apparatus connect to sockets on the Heat Transfer Experiments Base Unit. Ask us through the contact page to quote both together.
How does heat leave the bar?

Radial Heat Conduction Experiment
Radial Heat Conduction Experiment (Product Code: SLE/EA/25) is a teaching module used to study steady-state heat conduction outwards through a solid disc in engineering heat transfer laboratories. Mechanical engineering students use it to map the radial temperature profile, read by seven thermocouples set at equally spaced radii on a solid brass disc heated at its centre. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer of engineering lab equipment in India, at its own factory in Ambala.
Specifications
| Parameter | Detail |
|---|---|
| Test piece | Solid brass disc |
| Heat source | Electric heater at the centre of the disc |
| Heat sink | Circular cross-section cooling tube around the circumference of the disc |
| Temperature sensors | Seven thermocouples at equally spaced radii on the disc |
| Insulation | Around the disc, reducing heat loss by convection and radiation |
| Mounting | Base plate with a clear schematic of the experiment layout |
| Electrical connections | Heater and thermocouples plug into sockets on the Heat Transfer Experiments Base Unit |
| Cooling water | Cold water feed and drain for the heat sink, provided through the base unit |
| Product code | SLE/EA/25 |
| Manufacturer | Jain Scientific Equipments Pvt Ltd (ScienceLab) — OEM |
| Country of origin | India (made in Ambala, Haryana) |
What Is the Radial Heat Conduction Experiment Used For?
Students turn on the cooling water flow through the rim tube, then adjust the heater power and wait until the disc reaches equilibrium. At steady state, the seven thermocouple readings give temperature against radius from the hot centre to the cooled edge. Because the heat spreads through an ever-larger circumference as the radius grows, the temperature does not fall in a straight line, and students compare their curve with the logarithmic profile that Fourier's law predicts for radial conduction.
Typical practicals include estimating the thermal conductivity of the brass from the heater power and the measured temperature gradient, then repeating the test at a second heater setting to check consistency. The insulation around the disc limits convection and radiation losses, so results should match simple radial conduction theory — a good check on careful technique. The module suits lab equipment for technical institutes, polytechnics and university heat transfer courses.
What to Specify When Ordering
- Whether you already have the Heat Transfer Experiments Base Unit, since the module's heater and thermocouples connect to its sockets.
- The number of radial conduction modules needed for your student groups.
- Whether a cold water feed and drain are available at the bench for the heat sink.
- Any other optional experiments you plan to run on the same base unit.

Gay-Lussac's Law
Gay-Lussac's Law (Product Code: SLE/EA/27) is a bench-mounted apparatus used to show how the pressure of a fixed volume of air rises with temperature in engineering thermodynamics and physics laboratories. Students heat the air in a low-pressure vessel surrounded by an insulated heater under electronic control, then read absolute pressure, two air temperatures and their average on a digital display. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM and engineering lab equipment manufacturer, at its own factory in Ambala, India.
Specifications
| Parameter | Detail |
|---|---|
| Mounting | Bench-mounting, with a back plate that holds the vessel |
| Vessel | Low-pressure vessel holding a fixed volume of air |
| Heating | Insulated heater around the vessel, controlled by an electronic temperature controller |
| Controller sensor | Thermocouple measuring the heater surface temperature |
| Air temperature | Two thermocouples measuring the air inside the vessel |
| Pressure measurement | Pressure transducer measuring the pressure of the heated air |
| Display | Digital display of absolute pressure, both air temperatures and their average |
| Venting | Hand-operated valve at the bottom of the vessel to normalise the air to ambient conditions |
| Working gas | Normal clean, dry air (behaves as an ideal gas over the pressure range used) |
| Product code | SLE/EA/27 |
| Manufacturer | Jain Scientific Equipments Pvt Ltd (ScienceLab) — OEM |
| Country of origin | India (made in Ambala, Haryana) |
What Is the Gay-Lussac's Law Apparatus Used For?
Gay-Lussac's law, often called the pressure law, states that for a fixed mass of gas held at constant volume, pressure is directly proportional to absolute temperature. With this apparatus, students first open the hand-operated valve at the bottom of the vessel to bring the trapped air to ambient conditions, close it, and set the electronic controller for the temperature range the experiment needs. As the insulated heater warms the air, they record pressure from the transducer against the average of the two air thermocouples, then plot the results to prove the law.
Converting the readings to kelvin gives a straight line through the origin, while extending a plot of pressure against Celsius temperature back to zero pressure gives an estimate of absolute zero — a classic extension exercise. Ordinary clean, dry air is used because it behaves as an ideal gas over the pressure range of this equipment, so no special gas supply is needed. The unit suits engineering thermodynamics courses as well as colleges looking for advanced physics lab equipment in India.
OEM Manufacturer
Jain Scientific Equipments Private Limited trades as ScienceLab and is the OEM (original equipment manufacturer) of this Gay-Lussac's Law apparatus, which it makes at its own licensed factory at Saha, Ambala, Haryana, India. Dealing with the manufacturer directly helps when you need matching gas-law equipment for several benches, a repeat order for a later session or advice on spare parts — ask us and we will guide you.

Frequently Asked Questions
What does the Gay-Lussac's Law apparatus measure?
The Gay-Lussac's Law apparatus measures the absolute pressure of the heated air with a pressure transducer and its temperature with two thermocouples; a digital display shows the pressure, both air temperatures and their average. A further thermocouple on the heater surface feeds the temperature controller.
Why does the Gay-Lussac's Law apparatus use ordinary air?
The Gay-Lussac's Law apparatus uses normal clean, dry air because air behaves as an ideal gas over the range of pressures used in this equipment, so results follow the pressure law closely without any special gas supply.
What is the valve at the bottom of the Gay-Lussac's Law vessel for?
The hand-operated valve at the bottom of the Gay-Lussac's Law apparatus vessel lets students normalise the trapped air to ambient conditions before a run, so each test starts from room pressure and temperature.
Can students choose the temperature range on the Gay-Lussac's Law apparatus?
Yes. Students set the electronic temperature controller of the Gay-Lussac's Law apparatus for the range of temperatures needed during the experiment, and the insulated heater around the vessel warms the fixed volume of air through that range while they record the pressure changes.
Who manufactures the Gay-Lussac's Law apparatus?
The Gay-Lussac's Law apparatus (SLE/EA/27) is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory at Saha, Ambala, Haryana, India, and it is supplied factory-direct to institutions, dealers and importers.

Boyle's Law
Boyle's Law (Product Code: SLE/EA/28) is a bench-mounted apparatus used to prove that the pressure of trapped air varies inversely with its volume in engineering and physics laboratories. Students work hand-operated pumps that pressurise one of two clear-walled oil cylinders and so move a 'liquid piston' of oil in the other, while a mechanical gauge, a digital indicator and a thermocouple record pressure, air-column height and temperature. This Boyle law apparatus is made in India by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala.
Specifications
| Parameter | Detail |
|---|---|
| Mounting | Bench-mounting, with a back plate |
| Cylinders | Two clear-walled cylinders containing oil |
| Pressure control | Hand-operated pumps to increase or decrease the pressure in the left-hand cylinder |
| Liquid piston | Oil moving in the right-hand cylinder compresses or decompresses a trapped column of air in the test cylinder |
| Volume measurement | Digital indicator for the change in height of the trapped air column (height change × cross-sectional area = volume change) |
| Pressure measurement | Mechanical pressure gauge on the trapped air |
| Temperature measurement | Thermocouple and digital display for the trapped air temperature |
| Working gas | Normal, clean, dry air (behaves as an ideal gas over the pressure range used) |
| Product code | SLE/EA/28 |
| Manufacturer | Jain Scientific Equipments Pvt Ltd (ScienceLab) — OEM |
| Country of origin | India (made in Ambala, Haryana) |
What Is the Boyle's Law Apparatus Used For?
Boyle's law says that, for a fixed mass of gas at constant temperature, pressure multiplied by volume stays constant. Students pump in steps, reading the trapped-air pressure on the mechanical gauge and the change in air-column height on the digital indicator; multiplying that height change by the column's cross-sectional area gives the change in volume. Plotting pressure against the reciprocal of volume should give a straight line, confirming the inverse relationship.
The thermocouple matters because compressing air warms it: students watch the air temperature and pause between steps so it stays constant, which is the condition the law requires. The same readings let a teacher demonstrate how the air temperature changes during a quick compression or expansion. The apparatus is equally suited to university thermodynamics courses and to institutes sourcing TVET lab equipment in India.
OEM Manufacturer
The Boyle's Law apparatus is manufactured by its OEM, Jain Scientific Equipments Private Limited (trading as ScienceLab), at the company's own licensed factory at Saha, Ambala, Haryana, India. The company is a registered MSME whose major activity is manufacturing (Udyam UDYAM-HR-01-0003714), and export consignments are handled under Importer-Exporter Code AAECJ8618A issued by the DGFT. Buying straight from the maker keeps quotations, repeat orders and questions about replacement parts with the people who build the apparatus — just ask us.

Frequently Asked Questions
How does the Boyle's Law apparatus change the air volume?
The Boyle's Law apparatus changes the air volume with a 'liquid piston' of oil: hand-operated pumps raise or lower the pressure in the left-hand cylinder, pushing the oil in the right-hand cylinder up or down to compress or decompress the trapped air column.
How is volume measured on the Boyle's Law apparatus?
Volume on the Boyle's Law apparatus is worked out from the air-column height: a digital indicator measures the change in height, and multiplying it by the cross-sectional area of the column gives the change in volume, while a mechanical gauge reads the pressure.
Why does the Boyle's Law apparatus have a thermocouple?
The thermocouple and digital display on the Boyle's Law apparatus show the trapped air temperature, so students can keep it constant during tests as the law requires; the readings also help to demonstrate how air temperature changes during compression.
What gas does the Boyle's Law apparatus use?
The Boyle's Law apparatus uses normal, clean, dry air, which behaves as an ideal gas over the range of pressures used in this equipment, so no gas cylinder or special filling is needed for the experiment.
Who manufactures the Boyle's Law apparatus?
The Boyle's Law apparatus (SLE/EA/28) is made by its OEM, Jain Scientific Equipments Pvt Ltd (ScienceLab), at the company's own licensed factory at Saha, Ambala, Haryana, India, and is sold factory-direct to colleges, institutions, dealers and importers.

Cross Flow Heat Exchangers
Cross Flow Heat Exchangers (Product Code: SLE/EA/29) is a horizontal wind tunnel apparatus used to measure forced-convection heat transfer from a cylinder in a bank of rods in engineering heat transfer laboratories. Students replace any one rod of the working-section matrix with a copper element of known thermal capacity and a built-in thermocouple, then monitor how quickly it cools in the air flow. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM supplying lab equipment for technical institutes, at its own factory in Ambala, India.
Specifications
| Parameter | Detail |
|---|---|
| Configuration | Horizontal wind tunnel |
| Tunnel sections | Contraction cone, working section, diffuser, constant speed fan and exhaust with silencer |
| Air flow control | Variable slide valve |
| Working section | Series of rods arranged in a matrix at right angles to the air flow; any one rod can be removed |
| Test element | Cylindrical copper element of known thermal capacity with a built-in thermocouple |
| Inlet air temperature | Second thermocouple at the wind tunnel inlet |
| Air velocity | Pitot traverse measuring velocity at any vertical point, before or after the rods |
| Pressure tappings | Two static pressure tappings in the base of the working section, one before and one after the rods |
| Product code | SLE/EA/29 |
| Manufacturer | Jain Scientific Equipments Pvt Ltd (ScienceLab) — OEM |
| Country of origin | India (made in Ambala, Haryana) |
What Is the Cross Flow Heat Exchanger Used For?
In a cross flow heat exchanger one fluid passes at right angles to tubes carrying the other, and this apparatus models the air side of that arrangement with a rod bank inside a wind tunnel. Students place the copper element in the rod matrix, set the air flow with the slide valve and log the element temperature as it cools, while the inlet thermocouple gives the temperature of the incoming air. Because the element's thermal capacity is known, its rate of cooling gives the forced-convection heat transfer rate quickly, without a long wait for steady conditions.
Moving the element to different positions in the matrix shows how upstream rods disturb the flow and change heat transfer deeper in the bank. The pitot traverse maps air velocity at any height before or after the rods, and the two static pressure tappings give the pressure difference across the bank, so students can relate heat transfer to flow and pressure loss. It gives mechanical and chemical engineering departments a practical link between heat transfer theory and measurement, alongside our other engineering lab equipment in India.
OEM Manufacturer
Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM (original equipment manufacturer) of the Cross Flow Heat Exchangers apparatus and produces it at its own licensed factory at Saha, Ambala, Haryana, India. Because the wind tunnel, rod matrix and copper test element come from one manufacturer, questions about extra copper elements, replacement rods or repeat orders can be settled directly with the maker — just ask us. Universities, polytechnics, dealers and importers receive factory-direct quotations. More about the company is on the ScienceLab profile page.

What Is the Electric Forklift Circuit Trainer Used For?
Battery-electric forklifts are common in warehouses and manufacturing plants, and their faults are usually electrical: a weak battery, a failed relay or a motor drawing abnormal current. This simulator lets trainees run the drive and hydraulic functions from the operating and hydraulic levers and watch the voltage and current of each rotor change with demand. Comparing the two rotors side by side shows why lifting and travelling place different loads on the battery.
A typical practical asks learners to record normal input/output values at every component and then use them as the reference when tracing a fault. As an entry point to electric-vehicle concepts, it gives vocational colleges a practical industrial example before students progress to road-vehicle EV systems, making it useful vocational training lab equipment for material-handling courses. Always isolate the battery connector before touching terminals or wiring.

What Is the Yard Tractor Engine Fault Simulator Used For?
Port terminals, logistics yards and heavy-vehicle service centres rely on technicians who can diagnose large diesel engines quickly, and practising on a full-size engine is the most direct way to build that skill. On this system, trainees start the engine from the key switch, monitor oil pressure, voltage and current on the control panel, and use the 20-port diagnosis terminal and connector-checking socket to test sensors, actuators and the ECU. Mechanical checks — compression, belt tension, radiator cap pressure and leak testing — complete a service routine that mirrors real workshop practice.
Because the engine is much larger than those on passenger-car trainers, it gives students a realistic feel for heavy-duty cooling, fuel and charging systems. Use it as the capstone unit of a TVET heavy-vehicle curriculum, after learners have covered smaller diesel engines. Run it only with good ventilation or exhaust extraction, keep the stainless guards fitted, and let the cooling system cool before opening the radiator cap.
