Photodiode packaged in hermetically sealed UV glass window cap.
To operate your Solarmeter®, 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.
Proper Usage of Solarmeter® Ultraviolet Radiometer for Lamp Tests:
• Wear UV-block eye, face, hand protection when checking UVC lamps.
• Allow lamps to warm-up prior to taking readings (at least 5 min).
• Hold sensor close to lamp to measure individual lamp UVC intensity. Hold sensor at distance from lamp(s) for effective sterilization intensity.
• When checking aging of lamps, keep measuring distance and locations constant.
• Lamps should be replaced when output drops to about 70% of their original (new) readings.
• If unsure of what original new values were, replace a lamp with new one and compare old one.
Maintenance and care:
• Do not expose the meter to extreme temperatures, humidity, shocks or dust. If the meter is accidentally exposed to extreme humidity or damp conditions, unusually high readings may occur. Allowing the meter to dry naturally or placing it in a bag of silicate will restore normal function.
• Use a very soft cloth to clean the meter. Keep the sensor free of oil, dirt, etc.
