The CellaTemp® PK 51 was developed especially for temperature measurements in flame heated furnaces. Thanks to the selective spectral range of 3.9 µm, water vapour and CO2 in the pyrometer´s field of vision have no effect on the measuring results, even when measuring from large distances. This allows for precise measurements through flames and combustion gases.
