Radiometer Calibration Services

Conveniently located in Phoenix Arizona, ISO-CAL North America is ISO/IEC 17025 and ANSI/NCSL Z540 accredited for ‘both’ indoor and outdoor WRR traceable primary and secondary reference calibration. ISO-CAL’s indoors ASTM G207-11 compliant calibration process replicates the Hukseflux post production calibration method identically, thus maintaining sensitivity scale continuity from one calibration interval to the next, less any negligible naturally occurring sensitivity drift effect between calibration intervals. ISO-CAL states the expanded calibration uncertainty on each and every accredited calibration report generated, meeting or exceeding the manufactures original post production calibration uncertainty estimate.
