Sensor:
Silicon carbide (SiC) photodiode, housed in a hermetically sealed UV glass window cap. The interference filter coating blocks most of the UVA radiation, as shown in the spectral sensitivity diagram. Operation of the device:
To operate your Solarmeter®, position the sensor window on the top of the device directly toward a UV source.
Press and hold the pressure switch on the front of the device. For optimal results, note the distance of the measurement from the UV source to ensure repeatable results.
The battery operating voltage is adjustable from 9 V down to 6.5 V. Below 6.5 V, the numbers on the LCD display begin to fade, indicating the need for a battery replacement. With typical usage, a standard 9V battery lasts about 2 years.
Proper Use of the Solarmeter®:
• Wear eye protection when checking UV lamps (ideally, wraparound safety glasses).
• Allow lamps to warm up before taking measurements (at least 15 minutes).
• When checking lamp aging, use the same location and distance to ensure accurate readings.
Note: Model 5.0 (UVA + B) is best suited for lamp aging tests.
• Lamps should be replaced when output drops to approximately 70% of their original (new) readings. Measure total output in the center of the tanning bed with the lid closed, or check individual lamps with the lid closed. Track hours and readings in a log. • If the original new values are unknown, replace two adjacent lamps with new ones of the same type and compare readings. • To determine the percentage of UVB, divide the reading from Model 6.0 by the total UV (UVA + B) reading from Model 5.0. • For acrylic permeability testing, first take a reading through the acrylic panel. Then, remove the acrylic and hold the meter sensor at approximately the same distance from the lamp as the acrylic was. If the acrylic blocks too much UVB, it should be replaced. • When using this meter to compare different lamp types, readings should be considered relative rather than absolute due to variations in spectral power distribution. While higher-output lamps with a similar SPD generally show higher readings than lower-output lamps, lamps peaking at 290-300 nm will display higher readings than those peaking at 313 nm, even if their total UVB output is the same.
Care and maintenance:
• Avoid exposing the device to extreme temperatures, humidity, shocks, or dust.. If the device is accidentally exposed to excessive humidity or wet conditions, unusually high readings may occur. If you allow the device to dry naturally or place it in a bag with silica gel, normal function will be restored.
• Use a very soft cloth to clean the device. Keep the sensor free from oil, dirt, etc.
