Sensor:
The sensor consists of a GaAsP photodiode and a UV filter. It is completely insensitive to visible light longer than 400nm and infrared radiation, as its spectral sensitivity only covers the UVA range of 320-400nm.
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.
- Lamps should be replaced when the output falls to around 70% of their original (new) measured values.
- For curing lamps, hold the measuring device at the distance at which you want to cure your workpiece.
- To determine the total measured value in the middle of the sunbed, hold the measuring device upwards with the cover of the sunbed closed.
- To read individual lamps, hold the measuring device against the acrylic with the solarium cover open.
- This measuring device “sees” the UVA “tanning” rays. For erythematic measurements, use the model 7.0 MED/hr measuring device.
- For acrylic glass test measurements, carry out a measurement with and without acrylic glass at the same distance.
- When comparing different types of lamps, you should consider the measured values as relative and not absolute.
- Lamps that reach their peak value near 365 nm (newer models) have higher values than lamps that reach their peak value near 350 nm.
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.
