Availability date:
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).
