Configuration Options

Recommended when measurement accuracy is the top priority, the Hukseflux SR20 is a thermopile pyranometer that is compliant with the highest category in the ISO 9060 standard: class A (Secondary Standard).

This high-accuracy thermopile-based sensor measures global horizontal irradiance (GHI) and has a spectrally flat response across the full solar spectrum. The SR20 generates a small voltage signal that is proportional to the solar radiation flux, expressed in W/m^2.

The SR20 is compatible with all Symphonie series data loggers when equipped with a (SCM #6646, used with the and older) or Pro Signal Conditioning Module (P-SCM #9128, used with the SymphoniePRO Data Logger).

This sensor comes with a full sensor-specific characterization to the parameters of ISO 9060, calibration certificate, sun screen, and 5 m (16.4') cable. Note that as with all thermopile pyranometers, regularly scheduled maintenance is imperative to achieve the sensor’s specified performance.
