Sensor:
Silicon carbide (SiC) photodiode, housed in a hermetically sealed UV glass window cap. An interference filter blocks UV above the erythemal response, 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).
Hold the sensor close to the lamp or acrylic panel to measure the MED intensity of each lamp. Hold the sensor 25 cm above the bench under overcast skies to obtain results for a body position. – When checking lamp aging, keep the measurement distance and locations consistent. – Lamps should be replaced when the performance drops to about 70% of their original (new) measurements. Record the hours compared to the readings in a table. – If you’re unsure of the original new values, replace two adjacent lamps with new ones of the same type and compare the old values. – When testing acrylic transparency, measure through the acrylic panel; then remove the acrylic and hold the meter sensor at approximately the same distance from the lamp as the acrylic panel was. If the acrylic blocks a lot of UV, it should be replaced.
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.
