Sensor:
The semiconductor UV sensor consists of a photodiode chip and a UV filter. The sensor is completely insensitive to visible light longer than 400 nm and infrared radiation, as its spectral sensitivity only covers the UV range from 260 to 400 nm. Applications of the sensor include solar UV detection, as the spectral sensitivity is well adapted to the solar UV spectrum.
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®:
- When checking the UV transmittance of home, business, school or car windows, measure through the window or film and compare to outdoor readings. Note: The sensitive reading of the Model 5.7 only goes up to 1999 uW/cm², while full sunlight can exceed 5000 uW/cm² or 5.0 mW/cm² on a Model 5.0 meter.
- When measuring household lighting, measure near the lamps and increase the distance until the value falls below 1 W/cm².
- When measuring lighting in sports halls or stadiums, measure the values at floor level. Request the installation of UV protection if the readings are too high.
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.
