The sunshine duration sensor.

It precisely measures the direct solar irradiance that exceeds the threshold of 120w/m2, which is defined in the sunshine duration measurement method by WMO (World Meteorological Organisation), making it possible to measure highly accurate sunshine duration.
The sunshine duration meter is a one-of-a-kind high performance instrument, which is used worldwide in many applications such as ASOS (Automated Surface Observing System) by NOAA (National Oceanic and Atmospheric Administration).

Features

  • Very precise independent from atmospheric conditions.
  • Pyroelectric detector (300 nm – 2500 nm)
  • Economic solution to measure sunshine hours
