Solar radiometer SUV-B

UV

• For monitoring of UVB irradiance • Excellent directional response • Accurate temperature correction • Extremely low power consumption • RS-485 Modbus® RTU digital output • 0 to 1 V analog output • 5 year warranty SUV-B UVB Radiometer SUV-B is designed and optimized for the measurement outdoors of the UVB part of the solar radiation spectrum in the wavelength range from 280 nm to 315 nm. The innovative quartz diffuser provides improved directional response over the CUV5 and SUV5 models and the temperature correction is more accurate. The precision glass dome is the same as used in our CMP and SMP 10, 11 and 21 pyranometers. Unlike SUV5, the SUV-B is only available with a 0 to 1 V analog signal output; there is no 4-20 mA version. UVB typically accounts for 5% of the UV radiation that reaches the earth’s surface from a clear sky and it: affects the top layer of skin causes most sunburns is linked strongly to skin cancer damages DNA in skin cells burns unprotected skin in as little as 15 minutes SUV-B can typically measure the daily total of UVB irradiance with an uncertainty of 5%. A data file is supplied with the individually measured spectral response and a matrix of correction factors for variations in the solar zenith angle (air mass) and the atmospheric total ozone column. These can be used to reduce the measurement uncertainty.
