The semiconductor UV sensor consists of a photodiode chip and a UV filter. The sensor 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 of the sensor include solar UV detection, as the spectral response is well matched to the solar UV spectrum.
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 low level UV measurements:
• When checking home, business, school, or car window UV transmission, take reading through window or film and compare to outdoor reading. Note: The sensitive Model 5.7 reading only goes up to 1999 uW/cm², wheras full sunlight can exceed 5000 uW/cm²… or 5.0 mW/cm² on a Model 5.0 meter.
• For household lighting including compact fluorescents, take reading near lamps and again at several inches or feet distance, to see how far away the UV falls below 1 uW/cm².
• For gym or stadium lighting take readings at floor level. If concerned about amount of UV, ask the owners to have UV-block shields installed under the lamps.
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.
