CellaTemp - Model PX 15 -Stationary Pyrometer

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® PX 15 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. Interferences such as thickness changes, different types of glass or humidity changes do not affect the measured value at this wavelength.
