Sentec Sem228 solar light radiation meter 4-20mA silicone pyranometer

SEM228 solar radiation sensor adopts the photoelectric principle and can be used to measure the solar radiation with the spectral range of 0.3 ~ 3 μ M. Radiation sensor adopts high-precision photosensitive element, wide spectrum absorption, high absorption and good stability in the full spectrum range; meanwhile, dust cover with light transmittance up to 95% is installed outside the sensing element, The dust cover adopts special treatment to reduce dust absorption, effectively prevent the interference of environmental factors on internal components, and accurately measure the solar radiation.
