Setting New Standards In Electro-Optical Testing

CK-20A

The CK20A 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 CK20A includes a high precision digital thermometer, a type “S” thermocouple probe, an attachment for positioning the thermocouple in the blackbody cavity and software. The CK20A transfers the accurately measured temperature to the computer, via RS 232 link. The software rewrites the new calibration values into the SR20 controller, using IEEE-488 communication between the PC and the SR20/SR200.
