Description and Specification for Lab Tenders
Emissivity Measurement Apparatus.
The present Set-up is designed to measure the emissivity of test plate.
The test plate comprises of a mica heater sandwiched between two
circular plates. Black plate is identical with test plate, but its
surface is blackened. As all the physical properties, dimension and
temperature are equal; heat losses from both plates will be same except
radiation loss. Hence the input difference will be due to difference in
emissivity. Both plates are supported on individual brackets in a wooden
enclosure with one side glass to ensure steady atmospheric conditions.
