The LP PIRGO01 is manufactured by Delta Ohm. It is a pygreometer that is suitable for use in measurements of far infrared radiation or the FIR. It is especially designed for tough applications in the field of meteorology. It can also be used for the study of energy balance.
The FIR are taken from the measure of the thermopile output signal, and from the knowledge of the instrument temperature. The temperature measure is done by a 10kΩ NTC which is inside the body of the pyrgeometer. It has a wavelength range from 5.5 µm to 45 µm.
