A low-temperature blackbody source from -30 °C to 30 °C for industrial calibration
Original language description
A lot of industrial applications required infrared measurement of temperature on temperatures around ambient temperature or lowers temperatures. Measurements below 0 °C are complicated because of the ice coating created on the target surface, caused by presence of atmospheric moisture. These are main reasons why calibration of standard infrared thermometer utilizing these types of blackbodies is inconvenient even for industrial purpose. This fact was the start impulse for temperature laboratory at CzechMetrology Institute to developed own blackbody radiation source. This blackbody provides radiance temperatures in range from ?30 to +30 °C. The special effort was made to reduce of the effect of moisture and ambient reflection. Thanks to geometrical shape of cavity-depth and surface material, this blackbody has high emissivity. The design and construction of this source is presented with the results of the metrological characterization of the blackbody.
