G&R Labs offers NIST traceable calibrations for light meters and probes ranging from 220nm to 1100nm.
As light meter calibration specialists, all G&R Labs light meter calibration services are traceable to the National Bureau of Standards (NIST) with a +/- 0.5% in-house standard for radiometric calibrations and an in-house +/- 1.0% traceability for photometric calibrations. The 3 Sigma accuracy to the calibrated probe is +/-3.0% maximum, but G&R Labs standard is a +/-1.0% window from calibration to calibration. Calibration certificates are issued with all new calibrations and included within the calibration cost.
Also, G&R Labs provides photometric (eye response) calibrations for the majority of photometric meters on the market. Photometric calibrations are calibrated in Footcandles, Lux, Footlamberts, cd/m², etc.
One-Day Turnaround NIST traceable calibrations
G&R Lab has a one day standard turnaround time policy for meter calibrations. Ship it overnight to G&R Labs Monday and you can be back up and running by Wednesday.
G&R Labs light meter equipment is manufactured in an ISO 9001-2008 facility; We have an ISO 9001-2008 certification for our calibration and assembly operation.
