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, because its spectral response only covers the UVA region from 320-400nm.

Operation
To operate your Solarmeter, aim the sensor window located on the top panel of the meter directly at a UV source. Press and hold the push-button switch on the face of the meter. For best results take note of the distance the reading was taken from the UV source in order to ensure repeatable results. Battery operation voltage is viable from 9V down to 6.5V. Below 6.5V, the numbers on the LCD display will begin to dim, indicating the need for battery replacement. Under typical service load, a standard 9V battery will last approximately 2 years.


Proper Usage of Solarmeter® Ultraviolet Radiometer

  • Wear eye protection when checking UV lamps (Glasses that provide wrap around protection are ideal).
  • Allow lamps to warm-up prior to taking readings (at least 5 minutes).
  • When checking lamp aging, make sure to use the same location and distance to ensure accurate readings.
  • Lamps should be replaced when output drops to about 70% of their original (new) readings.
  • For curing lamps, hold the meter at the distance you intend your work piece to be cured.
  • To take the overall reading at the center of the tanning bed, place meter pointing up with canopy closed.
  • To take individual lamp readings, hold the meter against the acrylic with canopy open.
  • This meter is "seeing" the UVA "browning" rays. For erythemal readings use Model 7.0 MED/hr meter.
  • For acrylic testing, take readings with and without acrylic at a fixed distance.
  • When comparing different types of lamps consider readings to be relative rather than absolute.
  • Lamps that peak near 365nm (newer designs) will read higher than lamps that peak near 350nm.
  • Do not subject the meter to extremes in temperature, humidity, shock or dust.
  • Use a dry, soft cloth to clean the instrument. Keep sensor free of oil, dirt, etc.
