Hukseflux SR30-D1 pyranometer
The SR30 from Hukseflux provides class A (secondary standard) performance per ISO 9060:2018 along with a rich set of features that are unmatched by other sensors.
This all-digital sensor provides high-accuracy irradiance measurements with high data availability due to its integrated heating and ventilation functionality. Unlike traditional, externally heated and ventilated pyranometers, the SR30’s internal heating and ventilation system consumes relatively little power and still delivers high data availability.
In addition to hemispherical solar irradiance (with raw- and temperature-compensated outputs), the SR30 delivers the following value-added measurements:
- tilt
- internal temperature
- internal humidity
- fan speed
- heater current
All of this is made possible via the sensor’s Modbus RS-485 output, which integrates seamlessly with NRG’s SymphoniePRO Data Logger.
The SR30 comes with a full sensor-specific characterization to the parameters of ISO 9060:2018, calibration certificate, and sun screen (cable sold separately). Please note that as with all thermopile pyranometers, regularly scheduled maintenance is imperative to achieve the sensor’s specified performance.
