Applications of SOLARMETER® 4.2 :
• Window Film Tests
• Low Level UV from Household Lamps
• Ground-level UV from Stadium Lighting
• Outdoor Shady Area Readings
Features and Benefits of SOLARMETER® 4.2 :
• Hand Held Integral Sensor
• Accurate Calibration
• NIST Traceable
• Compact and Durable
• LCD Readout
Semiconductor UV sensor consisting of a silicon photodiode and UV filter.
The sensor is completely insensitive to visible light longer than 400nm and infrared radiation. Its spectral response covers only the UV region from 320-400nm.
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 :
• 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 μW/cm².
• 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.

SOLARMETER®, UV & VISIBLE LIGHT METERS
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!
Solar Light Company, Inc. is recognized worldwide for over 50 years as America's premier manufacturer of precision ultraviolet light sources, solar simulators, and radiometers. Our standard line of UV, visible, and IR radiometers and light meters measure laboratory, industrial, environmental, and health related light levels with NIST traceable accuracy. Column ozone, aerosol, and water vapor thickness measurements, in addition to long-term global ultraviolet radiation studies all over the world are performed using our atmospheric line of instrumentation. Solar Light also provides NIST traceable spectroradiometric analyses, calibrations for light meters and light sources, OEM instrumentation and monitors, and accelerated ultraviolet radiation degradation testing of materials.
