Hukseflux SR11 Pyranometer
Collect high quality solar irradiance data with the Hukseflux SR11 First Class Pyranometer.
Recommended for finance-grade solar resource assessment campaigns, the Hukseflux SR11 is a thermopile pyranometer that is compliant with first class criteria from the ISO 9060 standard for solar radiation measurement devices. This high accuracy thermopile-based sensor measures global horizontal irradiance (GHI) and has a spectrally flat response across the full solar spectrum. The SR11 generates a small voltage signal that is proportional to the solar radiation flux, expressed in W/m2.
The SR11 is compatible with all Symphonie series data loggers when equipped with a Symphonie® SCM Card (SCM #6646, used with the SymphoniePLUS®3 Data Logger or older) or Pro Signal Conditioning Module (P-SCM #9128, used with the SymphoniePRO® Data Logger).
This sensor comes with a 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.
