Radiometer Calibration Services
ISO-CAL North America provides a wide range of calibration services to meet any requirement, big or small. Indoors or out, our vast calibration capability allows us to select the most appropriate calibration method best suited to meet each customer’s specific application requirement, facilitating optimal measurement certainty at the field or laboratory testing level.
ISO-CAL North America maintains fully characterized Primary and Secondary reference radiometers, including NIST traceable spectral irradiance standards.
Laboratory service capabilities include the calibration of:
ISO-CAL North America operates two Primary Standard Absolute Cavity Pyrheliometers, traceable to the WRR (World Radiometeric Reference). The Absolute Cavity Pyrheliometer is the Primary Standard reference instrument to which all pyranometers and pyrheliometers are traceable. Both Absolute Cavity Pyrheliometers employ a new state-of-the-art control system developed by Campbell Scientific Inc. The compact portable control system features Campbell Scientific’s latest CR6 model data logger. The control system fully automates cavity operation, data processing and storage.
FEL Irradiance Standard
The FEL Standard Lamp provides absolute calibration of spectral irradiance from 250 – 1100 nm, serving as the primary reference for all spectroradiometer and UV radiometer calibrations.
