The albedometer consist of two integrated pyranometers and is an instrument for measuring the solar irradiance and albedo. every of the two thermopile sensor construction measures the solar energy that is received from the total solar spectrum and the whole hemisphere (180 degrees field of view). The output is expressed in Watts per meter square. The albedometer is designed for continuous indoor and outdoor use.
The albedometer does not require any power, it supplies a low voltage of 0-20mV in relation to the amount of incoming radiation. When a higher voltage level or a 4-20mA signal is required, the amplifier for pyranometer 469101 is the perfect solution.
