The Heitronics Model KT19.85 is used to remotely measure surface or cloud top temperature in the range of –50 to 200 °C. The principal of operation is the pyroelectric detection of infrared radiation emitted by the earth referenced to an internal black body source. The spectral range of the detector is 9.6 to 11.5 µm.
The accuracy of the Heitronics pyrometer is 0.5 K to a few K (@ -50 °C, 30ms) depending on measured temperature and integration time. Therefore integration time has to be chosen carefully to obtain best results.
