Hukseflux SR20 Secondary standard pyranometer

SR20 measures the solar radiation received by a plane surface, in W/m2, from a 180o field of view angle. SR20 enables you to attain the highest measurement accuracy and excels in demanding applications.

In order to improve overall measurement accuracy, Hukseflux effectively targeted two major sources of measurement uncertainty: calibration and “zero offset a”.
The initial calibration uncertainty is reduced to less than 1.2 %, an improvement of 15% relative to competing models.
The “zero offset a” specification of SR20 is 5 W/m2 unventilated. Competing models state 12 W/m2 unventilated and 7 W/m2 ventilated.

SR20’s low temperature dependence makes it an ideal candidate for use under very cold and very hot conditions. The temperature dependence of every individual instrument is tested and supplied as a second degree polynomial. This information can be used for further reduction of temperature dependence during post-processing. The incorporated heater reduces measurement errors caused by early-morning dew deposition.

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.
