Heat Absorption & Radiation Comparator
Heat Absorption & Radiation Comparator (Product Code: SLE/PHY/187) is a thermal radiation demonstration used to compare how a black surface and a shiny metal surface absorb and give out heat in school physics lessons. A 12 V bulb serves as the heat source for two parabolic metal bodies, one finished black and one shiny, each fitted with a thermometer holder. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the Heat Radiation Comparator Used For?
With the bulb switched on, students record both thermometer readings at regular intervals and find that the black body warms up faster, because a dull black surface absorbs radiant heat better than a shiny one. After the bulb is switched off, the readings show the black body also cooling faster, since good absorbers are also good radiators. It is a compact radiation experiment kit for classes in India studying heat transfer.
The result explains everyday choices such as black-painted solar water heater panels and shiny insulating surfaces. For fair results, use two matching thermometers, start both bodies at room temperature, keep the set-up away from draughts, and power the bulb from a suitable 12 V supply rather than the mains.
What to Specify When Ordering
- Two thermometers, since they are not included — tell us if you want them quoted.
- A 12 V supply for the bulb, if your lab does not already have one.
- Number of comparators, for a teacher demonstration or several student groups.
OEM Manufacturer
Jain Scientific Equipments Private Limited trades as ScienceLab and is the OEM (original equipment manufacturer) of this comparator, which it makes at its own licensed factory at Saha, Ambala, Haryana. The company is a registered MSME with manufacturing as its major activity (Udyam UDYAM-HR-01-0003714), and export consignments are shipped under Importer-Exporter Code AAECJ8618A issued by the DGFT.
Schools, colleges, dealers and importers in India and international markets order it direct from the factory rather than through a trader. Company background is on the ScienceLab profile.

Frequently Asked Questions
What does the Heat Absorption & Radiation Comparator include?
The Heat Absorption & Radiation Comparator includes a 12 V bulb heat source, two parabolic metal bodies (one black, one shiny) with two thermometer holders attached, and instructions. Thermometers are not included.
Do I need to buy thermometers separately?
Yes. Thermometers are not included with the Heat Absorption & Radiation Comparator, so you will need two for the attached holders. Tell us if you would like matching thermometers added to your quotation.
What power supply does the comparator need?
The Heat Absorption & Radiation Comparator uses a 12 V bulb as its heat source, so it should be run from a suitable 12 V supply, never directly from the mains. Ask us to quote a supply if you need one.
What result should students expect from the comparator?
With the Heat Absorption & Radiation Comparator, the black body normally heats up faster than the shiny body and also cools faster afterwards, showing that dull black surfaces are better absorbers and better radiators of heat.
Who manufactures the Heat Absorption & Radiation Comparator?
The Heat Absorption & Radiation Comparator is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as the OEM, at its own licensed factory in Saha, Ambala, Haryana, India.
Can ScienceLab export the comparator?
Yes. ScienceLab supplies the Heat Absorption & Radiation Comparator to schools and dealers in India and international markets, handling exports under its Importer-Exporter Code. Share the quantity and destination to receive a quotation.
