For determination of global radiation G. G=direct solar irradiance + diffuse
sky radiation on a plane surface. Use in deviating positions is possible. The
measuring system works independently of the ambient temperature in a spectral
range from 0,3 to 3 um.
Option to the starpyranometer. Its two functions are ventilation with the
help of an industrial ventilator and electric heating for supporting of the
ventilation during condensation of dew, rain and snow (switchpoint around
+10¡ÆC). Is has absolutly no influence on the measuring system of the
starpyranometer.
