Automatic Calibration Kit for Cavity Blackbodies

The CK-20 is a NIST (National Institute of Standards and Technology) traceable temperature calibration kit that enables
fully automatic or semi-automatic recalibration of CI’s high temperature cavity blackbodies.

The CK-20 includes the following items:

  • High precision digital thermometer
  • Thermocouple probe type “S”
  • CI’s automatic calibration software
  • Thermocouple holder for precise and repeatable positioning

The CK-20 transfers the accurately measured temperature
to the computer, via RS 232 link. The software rewrites the
new calibration values into the blackbody’s controller. CK-20
is compatible with all cavity blackbodies made by CI-Systems:
SR-20, SR-200 and SR-200N series.
