Sensor:
Silicon carbide (SIC) photodiode, packaged in hermetically sealed UV glass window cap. Interference filter blocks UV above the erythermal response as shown in the spectral response diagram.
Operating the meter:
To operate your Solarmeter® , point the sensor window on the top of the meter directly at 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 the UV lamps (goggles that offer all-round protection 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 with the sky closed to obtain results for a body position.
- When checking the lamp ageing, keep the measuring distance and the measuring locations constant.
- Lamps should be replaced when the output falls to around 70% of their original (new) measured values.
Record the hours compared to the measured values in a table. - If you are not sure how high the original new values were, replace two neighboring lamps with new ones of the same type and compare the old values.
- When testing the acrylic transmittance, measure through the acrylic sheet; then remove the acrylic sheet and hold the meter sensor at approximately the same distance from the lamp as the acrylic sheet was. If the acrylic blocks a lot of UV, it should be replaced.
Care and maintenance:
- Do not expose the measuring device to extreme temperatures, moisture, 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 meter. Keep the sensor free from oil, dirt, etc.
