H-3791 Silicon Pyranometer Sensor
The H-3791 Pyranometer is used to measure global solar radiation within all types of applications and studies. The sensor features a silicon photovoltaic detector mounted within a fully cosine-corrected miniature head. In clear unobstructed daylight conditions, (for which purpose the sensor was calibrated) the sensor compares favorably with first class thermopile type pyranometers. In most natural daylight conditions the error is ± 3%.
