Abstract
The paper describes the features of the measurements of the thermoradiation characteristics of materials: the absorption coefficient of solar radiation-αs and the emission coefficient – ε on compact integral devices: the FM 59M photometer and the TPM-I thermoradiometer. The results of the determination of αs, ε are compared. on the FM-59M photometer and TPM-I thermoradiometer with the results obtained on the basis of recording the reflection spectra on highprecision spectral devices. The main errors in the determination of αs, ε on the integral photometer FM-59M and thermoradiometer TRM-I are indicated, and methods for their elimination are proposed.
