Applications include monitoring UV lamp irradiance to help schedule maintenance and testing transmission of shielding, guarding and PPE.
Description
Sensor
The semiconductor UV sensor consists of a GaAsP photodiode chip and a UV filter which is completely insensitive to visible light longer than 400 nm and infrared radiation, since its spectral response covers only the UV region from 260 to 400 nm. Applications include solar UV detection (as the spectral response is well matched to the solar UV spectrum).
Operation
To operate your UV meter, aim the sensor window located on the top panel of the meter directly at a UV source. Press and hold the push-button switch on the face of the meter. For best results take note of the distance the reading was taken from the UV source in order to ensure repeatable results. Battery operation voltage is viable from 9V down to 6.5V. Below 6.5V, the numbers on the LCD display will begin to dim, indicating the need for battery replacement. Under typical service load, a standard 9V battery will last approximately 2 years.

Instructions for use
- Wear skin and eye protection when checking UV lamps.
- Allow lamps to warm-up prior to taking readings (at least 5 min).
- When checking aging of lamps, keep measuring distance and locations constant.
- Lamps should be replaced when output drops to about 70% of their original readings.
- If unsure of what original new values were, replace two adjacent lamps with new ones of the same kind and compare old ones.
- Do not subject the meter to extremes in temperature, humidity, shock or dust.
- Use a dry, soft cloth to clean the instrument. Keep sensor free of oil, dirt, etc.
