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.
