The CellaTemp® PA 60 is a digital ratio pyrometer for measuring temperatures from 300 to 800 °C. Due to the quotient measuring method, the device reacts less sensitively to disturbances caused by dust in the field of view, dirty protective screens or changing measuring surfaces than a spectral pyrometer. A through-the-lens sighting, a laser pilot light or a camera module are available for easy and precise sighting of the measurement object. The EERC (Extended Emissivity Ratio Correction) algorithm is used to compensate for the wavelength-dependent emissivity change when measuring aluminium or bare metals.
