The UV HAZARD RADIOMETER (Ultraviolet Safety Meter) is a hand-held laboratory and industrial grade instrument that measures the UV radiation hazard to eyes and skin. A valuable safety tool for any industry that involves worker exposure to UV radiation. It is sensitive to ultraviolet radiation specified as hazardous in standards published by the American Conference of Governmental Industrial Hygienists. Those standards state that the total UV exposure in an eight-hour period should not exceed 3 milliJoules per square centimeter at 270nm. Other wavelengths have hazardous potential related to that of 270nm by the Spectral Weighting Function (see figure available in this menu). The Safety Meter monitors the integrated effect of all ultraviolet wavelengths from the light source.
- CONFIGURATION - This Ultraviolet Safety Meter comes as a hand-held unit with a self-contained detector mounted on the top panel of the meter. It is activated by a sliding ON/OFF switch. The maximum safe exposure time in hours and 1/100 parts of an hour is shown on the LCD. A reading of 10.00 hours indicates a source too weak to reach the Threshold Limit Value during 8 hour working day.
