CellaTemp® PA 35 is a digital pyrometer for measuring temperatures ranging between 600 and 3000 °C. The short wavelength narrow band sensor works in a spectral region where neither sight path obstructions such dust or steam nor fluctuating emissivity will interfere with the measurement result. CellaTemp® PA 35 is especially suitable for detecting the temperature of metals (Tungsten, Molybdenum, etc.) and silicon wafers. CellaTemp® PA 35 features an integrated LED display, making it easy to view the temperature reading from a distance. Use the PC USB connection to set parameters such as emissivity and smoothing time constant or to perform diagnostics. Alternatively, emissivity can be set directly at the connection cable.
Features:
- Range: 600 to 3000 °C
- Focusable, interchangeable optics allow for precise distance adjustment
- Precision lenses with broadband antireflection coating
- Selective short-wavelength narrow-band spectral response
- Optimized to detect surface temperatures of metals and silicon wafers
- 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
