Sensor:
Silicon carbide (SiC) photodiode, packaged in hermetically sealed UV glass window cap. The interference filter coating blocks the majority of UVA radiation 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).
- When checking the lamp ageing, make sure that you use the same location and distance to ensure accurate readings.
- The lamps should be replaced when the output drops to approximately 50% of their original (new) readings. Measure the total output at a specific distance, or check individual lamps near the surface. Track the hours compared to the measured values in a table.
- If you are not sure what the original new values were, replace the lamp(s) with new ones of the same type and compare them with the old values.
- If you are testing the UVB transmittance of an acrylic pane, take the measurement through the acrylic pane. Then remove the acrylic pane and hold the meter sensor at approximately the same distance from the lamp as the acrylic pane was. If the acrylic disk blocks a lot of UVB, it should be replaced.
- When using this meter to compare different types of lamps, the readings should be considered relative rather than absolute due to their different spectral power distributions. Although higher wattage lamps with similar SPD will generally show higher readings than lower wattage lamps, lamps that peak at 290-300 nm will show higher readings than those that peak at 313 nm, even if the total UVB output of both lamps is the same.
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.
