The CellaTemp® PA 20 is a digital pyrometer for the measurement of temperatures from 250 to 2500 °C. Due to the very large measuring span, it can be used very universally for a wide range of applications. For easy and exact sighting of the measuring object, a through-the-lens sighting or a laser pilot light is available. 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.
