Product information "Double pyranometer (Albedomeer)"

The double starpile pyranometer is an instrument for measuring the solar irradiance and albedo. The thermopile sensor construction goes over blac and white surfaces and measures the solar energy that is received from the total solar spectrum and the whole hemisphere (180 degrees field of view top and bottom). The division in black and white parts is made for temperature compensation. The output is expressed in Watts per meter square. The pyranometer is designed for continuous indoor and outdoor use.

The Pyranometer does not require any power, it supplies a low voltage of 0-20mV in relation to the amount of incoming radiation. Optional a 4-20mA output is available.

For measuring of solar irradiance. Consist of two precision glas domes, two black and white thermopiles, chromed brass case and 3m cable.
