Calibrating to a higher standard
ISO/IEC 17025 accreditation assures customer confidence as our calibration standards, methods, and published uncertainties, are independently audited annually.
Our story
Founded in 2015, ISO-CAL North America is the largest one-stop solar radiometer (sensor) calibration service provider in North America by volume, offering calibration services on all major brand pyranometer and pyrheliometer models. We offer both indoor and outdoor ISO/IEC 17025 accredited primary and secondary transfer calibration services. Our emphasis is providing calibration services with the fastest turnaround times in the industry, while also achieving the lowest (best) calibration uncertainty estimates in the industry.
Measurement Accuracy Matters
Every ISO-CAL North America solar radiometer calibration report in addition to stating the before and after sensitivity result, also states the expanded calibration uncertainty estimate on the reported sensitivity value, expressed as a percentage (95% confidence interval). Expanded calibration uncertainty is an integral component to estimating sensor measurement uncertainty at the field level.
Solar Radiometer Calibration
ISO-CAL North America offers indoor and outdoor calibration services on all major brand pyranometer and pyrheliometer models. Additional services include outer dome replacement on select pyranometer models, as well as desiccant agent and bubble level replacement.
Other supported solar radiometer products include UV-A and UV-B radiometers, albedometers, net radiometers, FIR pyrgeometers, PAR, LUX, select spectro-radiometer models and more.

How it Works
Our RMA Process
Our online RMA (Return Merchandise Authorization) system greatly simplifies the return process for customers, as the system allows registered users to quickly generate RMA numbers for their sensor returns 24/7, as well as providing tracking info for their sensor returns.
Additional value-added system benefits include automated email notifications for any previously calibrated pyranometer that has come due for calibration. System registrants automatically receive an RMA report copy by email indicating their unique RMA# for each online RMA request submitted.
What is ISO/IEC 17025 Calibration?
ISO/IEC 17025 calibration is an international standard that outlines the general requirements for the competence of calibration and testing laboratories. This standard sets the criteria for the technical competence of these laboratories and provides a framework for quality management systems to ensure consistent and accurate results.
