In the range of 4.6 - 4.9 µm glass has an emissivity of almost 100%. Above 5 µm, atmospheric influences, such as humidity or water vapour, have an adverse influence on the measurement readings. The CellaTemp® PK 42 is provided with a blocking filter with a spectral sensitivity of 4.6 - 4.9 µm. allowing it to measure the temperature from the near surface area of the glass. Owing to its wavelength, changes in thickness, different types of glass, or varying moisture contents in the atmosphere do not affect the measurement reading.
