star pile pyranometer GR1200

The starpile pyranometer is an instrument for measuring the solar irradiance. 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). 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.
