ICE POINT BLACKBODY CAVITY FOR CHECKING THE PERFORMANCE OF AN INFRARED RADIATION THERMOMETER OPERATING NEAR 0 deg C

摘要

An ice point blackbody cavity has been designed and constructed at NML-SIRIM, Malaysia. It is a mean to measure the ice point reading of client's infrared radiation thermometer that operates near 0 deg C. The ice point check will predict the performance of the thermometer at other temperature range.
