STAR PYRANOMETER 8101

Star pyranometer for professional gathering of global radiation data in short-wave range. A dry part in the inner of the sensor prevents from water condensation. The horizontal mounting is easily done with three setscrews. The sensor corresponds to the international standards set by the World Meteorological Organization (WMO). As an option ventilation and heating can be attached to the sensor so that a save use throughout the whole year is ensured.
