<p><strong>Abstract.</strong> We report on the radiometric characterization and calibration of the TIR 100-2 (INGLAS Produktions GmbH, 2019) industrial emissometer. This instrument is used for handheld, on-site directional total emissivity measurements in industrial applications, e.g., the measurement of the emissivity of highly reflective thermal insulation materials. The diameter of the measurement field is determined by two different methods. The emissometer is calibrated with three
more » ... with three different sets of low- and high-emissivity reference samples. Each calibration is validated by comparing the results of the TIR 100-2 to directional total emissivity results of the Emissivity Measurement in Air Facility (EMAF) at the Physikalisch-Technische Bundesanstalt (PTB), Berlin. Finally, the hemispherical total emissivity of highly reflective thermal insulation materials is determined using the TIR 100-2 according to the European Standard EN 12898, and, again, the results are validated with results obtained at the EMAF.</p>
