Automatic Calibration Kit for Extended Area blackbodies

The CK-800 is a NIST (National Institute of Standards and Technology) traceable temperature calibration kit that enables fully automatic or semi-automatic recalibration of CI’s Extended Area blackbodies.
It achieves outstanding results by using the most advanced thermally stable electronic circuitry.
Temperature data of either the emitter, targets or the difference between them is digitally displayed.

The CK-800 includes:

  • A digital thermometer
  • PRT
  • CI’s automatic calibration software
  • Set of short and long master reference sensors
  • Additional two CK-800 sensors
  • Calibration certificate

CK-800 is compatible with all Extended Area blackbodies made
by CI-Systems: SR-800, SR-800R and SR-800N series.
