Pyrgeometer MS-20 is a scientific grade instrument designed to measure long-wave radiation. A special coated Silicon dome transmits incident radiation above 4.5µm by cutting off the shorter wavelengths of the Sun spectrum. The special meniscus shape provides 180°field of view. Due to very low window heating the MS-20 pyrgeometer can be used for daytime and nighttime measurements without need for shading.
With the optional MV-01 ventilator/heater the MS-20 can be operated free of condensation, frosts and snow in the harshest environmental conditions. Special albedo kit is available to measure net radiation.
MS-20 is supplied with WISG (World Infrared Standard Group) traceable calibration and 5 years warranty.
