The Pyranometer measures the solar radiation received by a plane surface from a 180° field of view angle. This quantity, expressed in W/m2, is called “hemispherical” solar radiation.

Pyranometer model is SR11 produced by Hukseflux Thermal Sensor Company. The solar radiation spectrum extends roughly from 285 to 3000 x 10-9 m. It is a high accuracy solar radiation sensor and it complies with the first class specifications of the ISO 9060 standard and the WMO Guide.It is connected directly to commonly used data logging systems. The irradiance, E, in W/m2 is calculated by dividing t-he SR11 output, a small voltage U, by the sensitivity S. The sensitivity is provided with SR11 on its calibration certificate. Traceability of calibration is to the WRR (World Radiometric Reference) maintained at the World Radiation Center in Davos, Switzerland.
