Optical Pyrometer - CellaTemp® PK 42 (500 – 2500 °C)

In the range between 4.6 ,4.9 µm, glass has an emissivity of almost 100 %. Above 5 µm, atmospheric influences such as humidity or water vapour affect the measurement. The CellaTemp® PK 42 has a blocking filter with a spectral sensitivity of 4.6 ,4.9 µm. It thus detects the temperature from the area near the surface of the glass. Thickness changes, different types of glass or humidity changes in the atmosphere do not affect the measured value at this wavelength.
