1. Safety instructions
The UV A/B sensor is not suitable for safety-related
applications.
• The UV A/B sensor may only be used for
educational purposes.
2. Description
Sensor box containing photodiode with built-in
optical filter to cut out visible light for
measurements in the UVA/UVB spectral regions.
Push-button selection of measurement ranges
70 mW/m², 7 W/m² or 700 W/m², with visible range
indicator.
Screw-on aperture cover to accommodate the
supplied UG-1 coloured glass insert to be used as a
UVA filter.
The sensor box and the selected measurement range
are detected automatically by the 3B NETlog
TM unit.
