Solar Light Company, Inc. UVB Biometer UVB-Model 501 Radiometer

The UV Bio meter model 501 is a meteorological grade instrument that measures UVB radiation outdoors and underwater (5m max depth). This permenant outdoor UVB measurements system is used in weather stations and meterological observatories world wide. Robertson Berger technology along with World Class manufacturing practices and NIST traceable calibrations ensure a high degree of reproducibility and comparability from unit to unit. All Radiometers have an analog voltage output which is proportional to the measured UV irradiance. In addition all 501 Radiometers have a controlled internal temperature that ensure a higher level of accuracy as compared to other units.
