Paper Abstract

By using an IR thermometer and a cylinder cavity with two walls, the space between which can be filled with water at a certain temperature, a simple and practical method is proposed to measure the emissivities of targets. The measurement principle is discussed and the formula for determining the emissivity is derived. In the experiment, several materials (targets) are used to carry out the measurement. It is shown that the experimental results are in good agreement with those obtained by an IR emission measurement instrument.
