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.
Correct use of the Solarmeter®:
– Wear eye protection when checking UV lamps (glasses offering full coverage are ideal).
– Allow the lamps to warm up before taking measurements (at least 15 minutes).
– When checking lamp aging, ensure that you use the same location and distance to ensure accurate readings.
– Lamps should be replaced when their performance drops to about 50% of their original (new) measurements. Measure the total performance at a specific distance, or check individual lamps near the surface. Track the hours compared to the readings in a table. – If you’re unsure of the original new values, replace the lamp(s) with new ones of the same type and compare them with the old values. – When testing the UVB transparency of an acrylic panel, take the measurement through the acrylic panel. Then remove the acrylic panel and hold the meter sensor at approximately the same distance from the lamp as the acrylic panel was. If the acrylic panel blocks a lot of UVB, it should be replaced. – If this meter is used to compare different types of lamps, the readings should be considered relative rather than absolute due to their different spectral power distributions. Although higher-power lamps with similar SPDs generally show higher values than lower-power lamps, lamps with a peak at 290-300 nm will show higher values than those peaking at 313 nm, even if the total UVB output of both lamps 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.
