The Emissivity Measurement Apparatus helps students determine the emissivity of different surfaces by comparing radiation heat transfer at various temperatures. It consists of test plates, heating elements, thermocouples, and a digital indicator for accurate data. Learners can study the relationship between temperature, emissive power, and surface finish. This apparatus provides hands-on experience in radiation heat-transfer experiments. Ideal for engineering colleges, polytechnic institutes, and ITIs, it offers durable design, precise control, and reliable academic performance.
