Precise Calibration Kit - Extended Area Blackbodies

The CK800R is used for precise calibration 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 CK800R includes a digital thermometer, PRT, CI’s automatic calibration software, calibration certificate and NIST traceability documentation.

  • Automatic Blackbody Calibration
  • RS232 communication
  • 0.001°C digital thermometer
  • NIST traceable
