Measuring principle
The surface to be measured is subjected to the thermal radiation of the black body at a temperature of 100°C for a short time. To obtain complete homogenous illumination of the measuring surface the radiator is designed in the form of a spherical half-space. This allows to measure rough and structured surfaces, too. A portion of the reflected radiation hits the radiation sensor through an opening in the radiator.
Determination of the emission level results from the comparison between the reflection values of the sample and the stored reference values of two calibrated standards.
The instruments are fabricated in Germany.
