pma2102.jpg (13788 bytes)The PMA2102 detector gives an accurate measurement of the biologically weighted ultraviolet radiation from sunlight or artificial light sources, also called sunburning UV radiation (SUV). Its spectral response follows closely the erythema action spectrum. The PMA2102 detector is designed to operate in outdoor environment. A built-in temperature sensor and compensation algorithm correct for the temperature coefficient of the UV sensor. A Teflon diffuser assures an angular response close to a cosine function for incident angles up to 50 making it suitable for measurements of diffuse radiation (sky radiation), often the major component of solar UV.
