Computerized Emissivity Measurement Apparatus (Product Code: SLE/MCE/71) is a thermal radiation experiment unit used to compare how strongly different metal surfaces emit heat in heat transfer and thermal engineering laboratories. Colleges looking for a radiation experiment kit at degree level choose it for its 20 mm aluminium, steel and copper samples with different finishes, heated by a 150 W halogen lamp focused through a parabolic reflector. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Emissivity Measurement Apparatus Used For?

Heat radiation is one of the three basic forms of heat transfer; unlike conduction and convection it travels as electromagnetic waves and can even cross a vacuum. In this apparatus a metallic sample sits on a thermocouple at the focal point of the reflector, is heated by the concentrated halogen beam, and the radiation it gives off is picked up by a thermopile. Comparing readings for anodised, nickel-plated, oxidised and painted samples at the same temperature shows students clearly how surface finish controls emissivity.

Moving the thermopile carriage to different distances lets the class examine how measured radiation intensity changes with distance from the sample. For consistent results, let each sample reach a steady temperature before reading, keep the thermopile face clean, and change hot samples only with tongs after the lamp has been switched off.

What to Specify When Ordering

• Power supply version: 230 V 50 Hz, 230 V 60 Hz or 120 V 60 Hz, single phase
• Whether extra aluminium, steel or copper samples are wanted for parallel student groups
• Number of units for the heat transfer laboratory

OEM Manufacturer

Jain Scientific Equipments Private Limited, which trades under the ScienceLab name, is the OEM of this emissivity apparatus. It manufactures the unit at its own licensed factory at Saha, Ambala, in Haryana, and sells it directly to universities, polytechnic institutes, laboratory dealers and importers.

Computerized Thermal Conductivity of Powder (Product Code: SLE/MCE/72) is a concentric-sphere apparatus used to determine the thermal conductivity of an insulating powder in heat transfer laboratories. As lab equipment for technical institutes, it lets mechanical and chemical engineering students measure radial heat flow between a 50 mm and a 100 mm radius copper sphere using ten embedded thermocouples. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Thermal Conductivity of Powder Apparatus Used For?

Heat produced by the coil inside the inner sphere can only escape outwards through the powder layer, so once temperatures are steady the electrical input (from the voltmeter and ammeter readings) equals the heat conducted through the insulation. Using the average inner and outer surface temperatures from the ten thermocouples and the two sphere radii, students calculate the powder’s thermal conductivity from the steady-state equation for a spherical shell.

The experiment is a practical way to compare insulating materials of the kind used on pipes, furnaces and cold stores. Raise the dimmer stat gradually, record all ten thermocouples only after the readings stop drifting, and respect the 95 °C temperature limitation. Repeating the test at two or three power settings is a simple check that the conductivity value is consistent.

What to Specify When Ordering

• Power supply version: 230 V 50 Hz, 230 V 60 Hz or 120 V 60 Hz, single phase
• The insulating powder you want to test, so the filling can be confirmed in the quotation
• The computerised data logging you expect, so the arrangement can be confirmed before ordering
• Number of units required

OEM Manufacturer

Free and Force Convection Apparatus (Product Code: SLE/MCE/73) is an air-duct experiment unit used to study natural (free) and forced convection heat transfer from heated surfaces in heat transfer laboratories. Among engineering lab equipment in India it is distinguished by four selectable heating elements of different geometries — a plate, two cylinders and a 23-tube element — tested in a 120 × 120 mm duct with an axial fan. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Free and Force Convection Apparatus Used For?

Air flows past the selected heating element and absorbs heat from its surface. With the fan off, air moves past the element by buoyancy alone (free convection); with the fan running, forced convection takes over and heat transfer rises with air velocity. Students record inlet and outlet air temperatures, element surface temperature, air velocity and heating power, then calculate heat transfer coefficients for each geometry and compare them with textbook correlations.

Because the elements release heat only at their surface and the unit is compact, they heat up quickly and each run is short, so a class can test several geometries in one session. Fit one element at a time, let temperatures settle at every fan setting, and keep element temperatures within the 90 °C limitation. Logging through the USB software keeps a complete record for the lab report.

What to Specify When Ordering

• Power supply version: 230 V 50 Hz, 230 V 60 Hz or 120 V 60 Hz, single phase
• A PC at the bench for the USB operating, data-acquisition and educational software
• Number of units, based on how many student groups will run convection practicals

Parallel and Counter Flow Heat Exchanger (Product Code: SLE/MCE/74) is a concentric-tube heat exchanger trainer used to compare parallel-flow and counter-flow operation and to determine the heat transfer coefficient in heat transfer laboratories. As engineering educational equipment for colleges and research laboratories, it combines two insulated stainless steel tube sections with a 3000 W heated hot-water tank, hot- and cold-water flow meters and data acquisition software. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Parallel and Counter Flow Heat Exchanger Used For?

In parallel flow the hot and cold streams enter at the same end and their temperatures converge along the tube; in counter flow they enter at opposite ends, so the cold outlet can approach the hot inlet temperature more closely. Switching between the two on the same exchanger lets students measure inlet and outlet temperatures of both streams, calculate the log-mean temperature difference, heat duty and heat transfer coefficient, and see for themselves why counter flow is usually more effective.

Changing the hot and cold water flow rates, and the hot water temperature through the temperature control unit, shows the effects of flow rate and temperature difference on performance. Let the hot water tank reach its set temperature before the first reading, keep both flows steady during each run, and use the data acquisition software to build a complete record for effectiveness calculations.

What to Specify When Ordering

• Power supply version: 230 V 50 Hz, 230 V 60 Hz or 120 V 60 Hz, single phase (note the 3000 W heater)

Cam Mechanism (Product Code: SLE/MCE/75) is a bench-top demonstration unit used to show how a rotating cam converts uniform rotation into non-uniform follower motion, with or without dwell, in theory of machines laboratories. Students fit one of four cam shapes and one of three engaging members, then read the follower stroke on a 0–30 mm dial gauge against the cam angle on a 360° scale. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Cam Mechanism Used For?

A cam is a shaped disc that pushes a follower through a planned motion as it turns, as in engine valve gear and automatic machinery. On this unit, students set the cam to successive positions on the angular scale and record the stroke on the dial gauge, building a displacement diagram of follower lift against cam angle. Repeating the test with the circular arc, tangent, hollow and asymmetric cams shows how the profile shapes the rise, dwell and return of the follower.

Swapping between the roller plunger, flat plunger and cam follower needs no tools, so the class can compare how each engaging member traces the same profile within one session. From the displacement readings, advanced students can estimate follower velocity and acceleration by differentiating the curve, a standard exercise in a kinematics of machines course. Keep the dial gauge plunger clean and square to the follower to make full use of its 0.01 mm graduation.

OEM Manufacturer

The Cam Mechanism is an OEM product of ScienceLab. Jain Scientific Equipments Private Limited, trading under the ScienceLab name, manufactures it at its own licensed factory at Saha, Ambala, Haryana, India, and sells it factory-direct to engineering colleges, polytechnics, ITIs, dealers and importers.

Because the maker handles each order, questions about extra cams, spare engaging members or repeat orders for more benches can be raised with us directly. The ScienceLab company profile explains more about the company as an engineering lab equipment manufacturer.

What followers can be used on the Cam Mechanism?
The Cam Mechanism accepts three engaging members: a roller plunger, a flat plunger and a cam follower. Both the cam and the engaging member can be exchanged without tools, so changeovers between tests take very little class time.

How are readings taken on the Cam Mechanism?
On the Cam Mechanism, the follower stroke is read on a dial gauge with a 0–30 mm range and 0.01 mm graduation, while the cam rotation is read on an angular scale from 0 to 360° with 1° graduation.
