UV Index Meter
Solar Light’s versatile NIST-Traceable PMA-Series Datalogging Radiometers / Photometers are designed for scientific professionals, offering unparalleled accuracy and flexible data management. These unit accepts over 85 different PMA21xx-Series sensors measuring UV, Visible, and IR wavelengths. Choose from the advanced Model PMA2100 Dual-Input Data Logging Radiometer or the standard Single-Input Model PMA2200.
The instrumentation used to measure UV index for the U.S. E.P.A./NWS program is directed toward the sky in a global normal (perpendicular to level ground) inclination. Therefore the Solarmeter® Model 6.5 is designed to operate in the same fashion. Solar irradiance measured this way includes direct (reduced by cosine law depending on solar zenith angle) plus diffuse (diffused by the atmosphere).
