UVA+B Meter Solarmeter Model 5.0 Standard

Solarmeter® Model 5.0 Standard UVA+B Meter

Portable Digital UVA+B Radiometer with Integral Sensor

Applications:
• Monitoring UV Lamp Intensity and Aging
• Acrylic Shield Transmission Testing
• Monitoring PUVA Therapy Lamp Intensity and Aging
• UV Blocking Capacity Testing of Glasses
• Outdoor UV Measurement
• Window Film/Tint Transmission Testing

Sensor
The UV semiconductor sensor consists of a GaAsP photodiode chip that is completely insensitive to longer visible light above 400nm and infrared radiation, as its spectral response only covers the UV region from 280 to 400nm. Applications include solar UV detection (as the spectral response matches well with the solar UV spectrum) and tanning lamps that peak near 365nm (such as "new era" and "high pressure" fluorescent lamps.)

Meter Operation
To operate your Solarmeter, point the sensor window located on the top panel of the meter directly towards a UV source. Press and hold the button switch on the face of the meter. For best results, note the distance from which the UV source reading was taken to ensure repeatable results.

Battery operation is viable from 9V down to 6.5V. Below 6.5V, the numbers on the LCD display will begin to dim, indicating the need to replace the battery. Under typical service load, a standard 9V battery will last approximately 2 years.

Proper Use of Solarmeter® UV Radiometer
• Use eye protection when checking UV lamps. Wrap-around glasses are ideal.
• Allow lamps to warm up before taking readings (at least 5 minutes).

Lamp Aging
• 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 approximately 50% of their original (new) readings.

Curing Lamps
• For curing lamps, hold the meter at the distance you intend to cure your workpiece.

Tanning Lamps
• For overall reading in the center of the tanning bed, place the meter pointing upwards with the cover closed.
• For individual lamp readings, hold the meter against the acrylic with the cover open.
• This meter is "seeing" the "tanning" UVA rays. For erythemal readings, use the Model 7.0 MED/hr meter.

Solar Bed Acrylic Testing
• For acrylic testing, take readings with and without acrylic at a fixed distance.

General
• Lamps peaking near 365nm (newer designs) will show higher readings than lamps peaking near 350nm.
• Do not expose the meter to extremes of temperature, humidity, shock, or dust.
• Use a dry, soft cloth to clean the instrument. Keep the sensor free of oil, dirt, etc.
