SOLAR SERIES RADIOMETERS 6.5
The 6.5 measure via a Silicon Carbide (SIC) Photodiode packaged in hermetically sealed UV glass window cap (the 5.0 uses GaAsP photodiode chip and UV filter).
Solar 6.5 measures environmental (outdoor) solar intensity (290-400nm, peaking between 297-310nm) and provides LCD readout in mW/m² SUV/25 (the WMO international standard for displaying erythemally weighted irradiance on a 1-15 scale).
Point the meter at the UV light source (leakage) and record reading.
Calibrated to accuracy standards referenced to NIST.
