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

  • To measure home, business, school or car window UV transmission, take reading through window or film and compare to outdoor reading.
  • For household lighting, including compact fluorescents, take reading near lamps and increase distance until reading falls below1 W/cm.
  • For gym or stadium lighting, take readings at floor level. Ask to have UV shields installed if readings are too high.
  • 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.
