Setting New Standards In Electro-Optical Testing


The CK-200 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-200 includes a high precision digital thermometer, a type “S” thermocouple probe, an attachment for positioning the thermocouple in the blackbody cavity and software. The CK-200 transfers the accurately measured temperature to the computer, via RS 232 link. The software rewrites the new calibration values into the CK-200 controller, using IEEE-488 communication between the PC and the SR200.
