The CellaTemp® PX 20 is a digital pyrometer for measuring temperatures from 210 to 2500 °C. Due to the very large measuring span, it can be used very universally for a wide range of applications. A through-the-lens sighting or a laser pilot light is available for easy and precise sighting of the measuring object. Parameters such as emissivity, measuring range or smoothing constants can be set with the rear buttons. The changed parameters are shown on the LED display. In normal operation, the current measuring temperature is displayed.
