Abstract

A portable instrument for measuring the mean emissivity in the spectral range 0.6µm to 40µm has been developed for quality control purposes. The paper presents the working principle and the design of the instrument as well as results of calibration measurements. The instrument has proved to measure emissivities with an accuracy better than ±0.03.
