Article description

The CellaPort PT 135 has a very short-wave and narrow-band spectral sensitivity. Therefore, the pyrometer reacts to interfering influences such as signal weakening by dust, vapour or smoke in the pyrometer's field of view, to soiling of the protective window as well as to fluctuations in the emissivity of the measuring object much less than a conventional spectral pyrometer. Metals have the physical property that the emissivity increases with shorter radiation wavelengths and higher object temperatures. Therefore, the CellaPort PT 135 is ideal for precise measurement of metals and very hot objects. In addition, the pyrometer is used to measure thin semiconductors, as semiconductors have very good radiation properties in the pyrometer's special spectral range. For wavelengths > 1 µm, silicon is transparent, so a standard pyrometer would measure the temperature of the material behind it through the silicon.

Special features:
  • Measuring range 600 to 3,000 °C
  • focusable interchangeable lenses for exact adjustment of the measuring distance
  • broadband anti-reflective precision lenses
  • short-wave and narrow-band spectral range
  • particularly suitable for precise measurements on metals and on silicon wafers
  • LED display
  • standard feature: USB interface

Emissivity calculator

The correct emissivity to be set on the pyrometer is calculated from the measured value displayed on the pyrometer, the true object temperature, the emissivity preset at the pyrometer and the ambient temperature (required for some instrument types).
The value displayed by the pyrometer is calculated from the true object temperature, the emissivity of the measurement object, the emissivity set on the pyrometer and the ambient temperature (required for some instrument types).
