EMISSIVITY MEASUREMENT APPARATUS-
Model Number : VIPL-HT-05
Detail Specification as per following page.
EXPERIMENTATION:
Measurement of emissivity of non‑black surface over a range of temperatures.
DESCRIPTION:‑
Experimental setup consists of two circular plates identical in size and are provided with heating coils. The plates are kept in an enclosure and heat input can be varied by regulators and is measured by an ammeter and voltmeter. Each plate has thermocouple and one to read the chamber temperature. One plate is blackened by a layer of enamel black paint to form the idealized black surface whereas the other plate is the test plate. The aim is to measure the emissivity of the test plate surface.
FEATURES :
- Digital Temperature Indicator for Temperature Measurement.
- Complete panelized instrument for electric input
- seven Thermocouples to obtain temperature distribution clearly.
