Owing to our expertise and domain knowledge, We at “Global Luminous” have been able to offer Emissivity Measurement Apparatus at an industry leading price. This apparatus is precisely manufactured under the supervision of expert professionals using best quality raw material. Appreciated for easy installation, simple functionality and hassle-free operation, this apparatus is hugely demanded by the clients.
- 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 glass 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 variacs so that temperatures of both can be kept equal and is me asured with Digital Voltmeter and Digital Ammeter.
