Radiation Absorption Kit Manufacturer,Supplier and Exporter in India
Product Code : EL-MTP-11678
The radiation absorption kit is a classroom heat-radiation experiment set used for showing how absorption and emission depend on surface colour and texture. It includes four aluminium discs with different finishes and liquid crystal thermometers, helping students compare matt, mirror, black and silver surfaces through visible temperature change.
Product Description
The Radiation Absorption Kit from School Equipments India is designed for practical lessons on heat transfer, infrared radiation and materials and their properties. Each aluminium disc has a different durable finish: matt black, mirror black, matt silver or mirror silver.
A liquid crystal thermometer is bonded to the reverse of each disc. The thermometer measures from 30°C to 65°C in 5°C increments, making temperature change easy to read during classroom demonstrations. The discs respond quickly to infrared radiation or bright light, so teachers can complete several comparative experiments in one lesson.
Key Features
- Set of 4 discs: Includes matt black, mirror black, matt silver and mirror silver aluminium discs.
- Liquid crystal thermometers: Each disc has a rear thermometer measuring 30°C to 65°C.
- 5°C increments: Clear temperature steps support quick classroom comparison.
- Surface comparison: Demonstrates how colour and texture affect heat-radiation absorption.
- Fast response: Reacts quickly to infrared radiation or bright light for efficient lessons.
- Multiple investigations: Supports cooling-rate, filter, reflector, inverse-square-law and absorption-emission activities.
- Organised storage: Supplied with a holder in a storage box.

Applications / Uses
- Investigating how surface colour affects heat absorption
- Comparing matt and mirror finishes under the same heat source
- Studying rates of cooling from different surfaces
- Testing the effect of filters and reflectors on radiation transfer
- Demonstrating inverse square law relationships with heat radiation
- Exploring equilibrium between absorption and emission

How to Use the Radiation Absorption Kit
- Place the four discs in the holder with the finished surfaces facing the heat or light source.
- Position the discs at the same distance from the infrared source or bright lamp.
- Begin heating and observe the liquid crystal thermometer on the reverse of each disc.
- Read the indicated temperature when the thermometer segment appears green.
- Record the temperature of each disc at fixed time intervals.
- Compare the results for black versus silver and matt versus mirror surfaces.
- Repeat the experiment with filters, reflectors or different distances where required.
Safety and handling: Remove the heat source immediately if “STOP” appears on the thermometer. Avoid overheating, do not touch hot discs directly, and use only teacher-approved light or infrared sources.
Care & Maintenance
- Allow discs to cool fully before handling or storage.
- Clean surfaces gently with a soft, dry cloth to protect the finishes.
- Do not scratch, bend or peel the liquid crystal thermometers.
- Return the discs to the holder and storage box after each lesson.

Frequently Asked Questions
What is a radiation absorption kit used for?
A radiation absorption kit is used to compare how different surfaces absorb and emit heat radiation. It helps students see why colour and texture affect temperature change.
How many discs are included in the kit?
The kit includes four aluminium discs: matt black, mirror black, matt silver and mirror silver.
What temperature range do the thermometers measure?
Each liquid crystal thermometer measures from 30°C to 65°C in 5°C increments.
How do you read the liquid crystal thermometer?
The indicated temperature is read when the thermometer segment appears green. During heating, segments may appear brown, then green, then blue, before returning to black.
Can the kit demonstrate the inverse square law?
Yes. The manufacturer states that the discs can be used to investigate inverse square law effects by changing the distance from the radiation source.
What should I do if STOP appears on the thermometer?
If “STOP” appears, remove the heat source immediately. This prevents overheating and protects the liquid crystal thermometer.
