The CellaTemp® PA 60 is a digital two-colour pyrometer for measuring temperatures from 300 to 800 °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.
Features:
- Range: 300 to 800 °C
- Focusable, interchangeable optics allow for precise distance adjustment
- Precision lenses with broadband antireflection coating
- Short wavelength spectral response
- LED display is easy to read from a distance
- Test current can be applied to perform diagnostics
- Signal processing: two analogue outputs and USB / RS485 interface.
