Radiometer UVA - A Hand Held Digital UVA Radiometer.
SOLARMETER MODEL 4.0 - UVA.
This product is no longer in stock
Applications of SOLARMETER 4.0 :
• UV Lamp Aging Test
• Acrylic Shield Transmission
• Eyewear UV Block Comparison
• Window Film/Tint Transmission
Features and Benefits :
• Hand Held Integral Sensor
• Accurate Calibration
• NIST Traceable
• Compact and Durable
• LCD Readout
The sensor consists of a silicon 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. Applications include solar UV detection as a spectral response is well
matched to the solar UV spectrum.
Meter 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 around 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).
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 about 70% of their
original (new) readings.
Curing Lamps :
• For curing lamps, hold the meter at the distance you intend your work piece to be cured.
Tanning Lamps :
• 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 ather 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.

Model 4.0 : UVA Radiometer
Solarmeter® is Solar Light Company Inc.'s brand of specialty hand-held light meters. We are the industry leader in the design and manufacture of UV and Visible Light radiometers for measuring lamp irradiance vs aging, as well as other related applications serving the indoor tanning industry, window film tint measurement, outdoor UV Index measurement, UV curing, reptile and sterilization lamp measurement, red/blue light phototherapy, LED measurement, and photovoltaic (PV) solar irradiance metrology. These meters provide long term accurate measurements for both low and high intensity lamp systems, in order to enable output and aging determination. They also measure solar irradiance.
Since 1991, well over 30,000 of these hand-held digital meters have been produced and sold worldwide.
Each Solarmeter® radiometer model comes complete with a carrying case and instruction brochure. Models 4.0 through 9.6 include a NIST-traceable Calibration Certificate, while Model 10.0 includes a WRR-traceable Calibration Certificate.
Generally, lamps need replacement when their output declines 30% (falls below 70% of their new values.) This may occur after anywhere from a few hundred to >1000 hours of use, depending on many various factors. The only way to know for sure is to monitor irradiance with a meter!
