The precision UV-A Radiometer MS-212A is designed to measure UV-A radiation with high reliability. It is calibrated against a NIST traceable standard. The combination of a well-designed UV-A filter and a GaAsP photodiode guarantees high performance to measure UV-A between 315 and 400nm. The energy in this spectral range accounts for 4 to 5% of the total solar radiation.
