INTRODUCTION

SPECIFICATIONS

The Sper Scientific UVC Light Meter (Model

850010) is a light-weight, portable instrument
that measures damaging UV (ultraviolet) light in
both natural and manmade environments.

The UV Light Meter measures short wave UV-C
light for applications such as UV light fume
hoods, UV sterilization, industrial glass and non­destructive testing.

You can use the meter almost anywhere to
determine UV light intensity and avoid the
harmful effects of overexposure.
