Stationary pyrometer

Two-colour pyrometer PX 50

The CellaTemp^® PX 50 is a digital two-colour pyrometer for measuring temperatures from 500 to 1400 °C. Caused by the quotient measuring method, the device is less sensitive to disturbances due to dust and steam in the field of view, soiled protective windows or changing surfaces as a one-colour pyrometer. For easy and precise targeting of the measuring object, a through-the-lens sighting, a laser spot light or a Video camera is available.
