CellaTemp® PA 28 is a digital pyrometer for detecting temperatures ranging from 75 to 650 °C. CellaTemp® PA 28 was specially designed to detect the temperature of shiny reflective metal objects at very low temperatures.
Features:
- Range: 75 to 650 °C
- Digital input / output
- Focusable optic allow for precise distance adjustment
- Precision lenses with broadband antireflection coating
- LED display is easy to read from a distance
- Test current can be applied to perform diagnostics
- Signal processing: two analogue output and USB / RS485 interface
