3 Intended use
Due to its high emissivity (ε ≥ 0,995) which is independent of wavelength in the
infrared range, SW40 / SW40NT is suitable for calibrating infrared radiation
thermometers, LineScanner and thermal imaging cameras. The device to be
calibrated is positioned in front of the radiator aperture. The radiated temperature is
determined either with a reference radiation thermometer or with a contact probe
(e.g. with a 3 mm Pt100). The materials of the radiator are designed for temperatures
from -20 to 150 °C. You must set up a protection against contact above temperatures
of 110 °C.
Set up a protection against contact when operating the radiator above 110 °C.
