Pyranometers

rnrg offers various types of pyranometers to suit any resource assessment campaign.hukseflux sr20 pyranometer

 

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: 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/m2.

the sr20 is compatible with all symphonie series data loggers when equipped with a symphonie® scm card (scm #6646, used with the symphonieplus®3 data logger 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.
