  • High temperature stability
  • Small dimensions
  • Stainless steel housing 

Details

The calibration sources of type IRC 45 to IRC 150 are instruments for inspection of the measurement accuracy of pyrometers (radiation thermometers) at a fixed temperature value. The highly accurate controlling ensures a constant and stable heating of the large emitter surface with a high temperature uniformity with a maximum deviation of 0.2 °C. This enables in combination with the high emissivity of the emitter surface at 98% also the exact verification of pyrometers with larger spot sizes.

The robust stainless steel design guarantees the operation even under rough industrial environments. The compact dimensions also enables the checking of fixed installed pyrometers at the measuring location.

Typical Calibration Applications

  • Single point temperature calibrations of point IR pyrometers
  • Fixed mount and portable pyrometer calibration verification
