Silicon Carbide (SiC) Photodiode. Interference filter blocks most UVA from response as shown on the Spectral Sensitivity Graph.
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:
• Wear tinted eye wear when checking intense light sources. (Glasses that offer all-round protection are ideal.)
• Allow lights to warm-up prior to taking readings (at least 15 min).
• When checking aging of lamps, keep measuring distance and locations constant.
Note: Model 5.0 (UVA + B) is best for lamp aging tests.
• Lamps should be replaced when output drops 30% to about 70% of their original (new) readings. Take overall reading center of tanning bed bench pointing up with canopy closed, or check individual lamps at acrylic with canopy up. Keep track of hours vs. readings on a chart.
• If unsure of what original new values were, replace two adjacent lamps with new ones of the same kind and compare to old ones.
• To determine percent UVB divide Model 6.0 reading by Model 5.0 total UV (UVA + B) reading.
• When checking acrylic transmission, take reading through acrylic; then remove acrylic and hold meter sensor at approximately the same distance from lamp as the acrylic shield was located. If acrylic blocks much UVB it should be replaced.
• When using this meter to compare different type lamps, due to their different spectral power distributions, the readings should be considered relative rather than absolute. Although higher output lamps of similar SPD’s will generally read higher than lower output lamps, ones that peak near 290-300 nm (as does the meter response) will read higher than ones peaking near 313 nm even if the total UVB output of both is the same.
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.
