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 enclosure with one side transparent to ensure steady atmospheric conditions.
Temperature Sensors are provided to measure the temperature of each plate and surrounding. Electric Supply is given to heaters through separate variances and is measured with Digital Voltmeter and Digital Ammeter.
