Solar radiation at 0.3~3μm. The radiation sensor adopts high- photosensitive , wide spectrum absorption, full The total solar radiation sensor uses the photoelectric principle to measure the range High absorption and good stability in the range; At the same time, a dust cover with a light transmittance of up to 95% is installed outside the sensing . The dust cover adopts special treatment to reduce dust adsorption, effectively prevent the interference of environmental factors on the internal components It is enough to measure the amount of solar radiation more accurately., Weight: 0.66579603124 pounds, Manufacturer: Tuidzljd
