The CellaTemp® PX 60 is a digital ratio pyrometer for measuring temperatures from 300 to 1000 °C. The ratio measurement method responds to the surface temperature. Due to the quotient measuring method, the instrument is less sensitive to interference from 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.
