Sensor:
The sensor consists of a GaAsP photodiode and a UV filter. It is completely insensitive to visible light longer than 400nm and infrared radiation, because its spectral response only covers the UVA region from 320-400nm.
Operation:
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:
• To measure home, business, school or car window UV transmission, take reading through window or film and compare to outdoor reading.
• 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.
