Photodiode packaged in hermetically sealed UV glass window cap.
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 UV protection for eyes, face and hands when checking UVC lamps.
- Allow the lamps to warm up before measuring (at least 5 minutes).
- Hold the sensor close to the lamp to measure the UVC intensity of each lamp. Hold the sensor at a distance from the lamp(s) to measure the effective sterilization intensity.
- When checking the lamp ageing, keep the measuring distance and the measuring locations constant.
- The lamps should be replaced when the output falls to around 70% of their original (new) measured values.
- If you are not sure what the original new values were, replace a lamp with a new one and compare the old values.
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.
