MS-093 Sunshine Duration Sensor

MS-093 Sunshine Duration Sensor

Features

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

EKO Sunshine Duration Meter MS-093 has a specially designed and rotating mirror, which reflects the direct solar radiation onto an especially flat spectral response pyroelectric sensor and measures the sunshine duration by pulse signals.

MS-093 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 Organization), making it possible to measure highly accurate sunshine duration.

EKO Sunshine Duration Meter MS-093 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).
