Pyrometer CellaTemp PA 21

Article description

The CellaTemp® PA 21 is a digital pyrometer with fibre optic cable for measuring temperatures between 300 and 2,000 °C. The pyrometer is equipped with a separate optical measuring head and a fibre optic cable. The fibre optic cable and measuring head are insensitive to interference from electromagnetic radiation and can be used in ambient temperatures up to 250 °C without cooling. The variant with separate optical measuring head has advantages especially in confined spaces.

Special features:
  • Measuring range 300 to 2
  • 000 °C -- focusable interchangeable lenses for exact adjustment of the measuring distance -- broadband anti-reflective precision lenses -- short measuring wavelengths -- LED display can be read from a great distance -- test current output for the diagnostic function -- standard feature: analogue output and USB/RS485 interface -- measuring head and fibre optic cable heat resistant up to 250 °C
