Suitable for the measurement of global radiation G
G = direct solar irradiance + diffuse sky radiation on a plane surface (W/m2)
* "First class" according to WMO and ISO 9060 |
* world-wide market-leader |
* independent from ambient temperature |
* all-season measurements |
The measuring principle of the starpyranometer is the measurement of, the temperature difference between white and black painted sectors. By that means the measuring result is not affected from ambient temperature. A precisely cut dome shields the sensing elements from environmental factors.
A drying cartridge keeps the interior free from humidity. An optional protective housing (Model no. 8106) enables measurements even in cold weather.
The pyranometer is supplied with a spirit level and 3 levelling screws for accurate levelling.
All pyranometers are supplied with a calibration certificate.
