ISO 9060 pyranometer SR20

secondary standard

The SR20 pyranometer uses a state of the art thermopile sensor with black coated surface, two domes and an anodised aluminium body. The connector, desiccant holder and sun screen fixation are ultra robust and designed for industrial use. All parts are specified for use across SR20’s entire rated operating temperature range. Pyranometers are subject to classification in three classes according to ISO 9060. From second class to first class and from first class to secondary standard, the achievable accuracy improves by a factor 2. Measurement accuracy does not only depend on instrument properties, but also on measurement conditions. A very accurate instrument will quickly underperform without a regular schedule of maintenance. The selection guide assists the user in choosing the right instrument. Whatever the application is: Hukseflux offers the highest accuracy in every class at the most attractive price level.
