The Sper Scientific UVA/B Light Meter (Model
850009) is a light-weight, portable instrument
that measures damaging UV (ultraviolet) light in
both natural and manmade environments.
The UV Light Meter measures long and medium
wave UV-A/B light for applications such as
forensics, chromatography, electrophoresis and
dermatology.
You can use the meter almost anywhere to
determine UV light intensity and avoid the
harmful effects of overexposure.
