Applications of SOLARMETER 7.5 :

• W/m² Erythemal Lamp/Sun Output
• Check EU Tanning Regulation 0.3 W/m² Limit
• Acrylic Shield Transmission
• Eye Wear UV Block Comparison

Features and Benefits of SOLARMETER 7.5 :

• Hand Held Integral Sensor
• Accurate Calibration
• NIST Traceable
• Compact and Durable
• LCD Readout

Sensor :

Silicon Carbide (SiC) Photodiode in hermetically sealed UV glass window cap.
Interference filter blocks UV above erythemal response as shown on Spectral Sensitivity Graph.

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 tanning beds place meter at body position. For best results take note of thedistancethe 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).
• 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.
• To take the overall reading at the center of the tanning bed, place meter pointing up with canopy closed.
• To take readings at body position, hold the meter about 25cm above the bench with canopy closed.
• To take individual lamp readings, hold the meter against the acrylic with canopy open.
• If you are unsure of original lamp values, replace two adjacent lamps identical new ones and compare.
• When comparing different types of lamps consider readings to be relative rather than absolute.
• 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.
• Note: The black dot on the LCD is a decimal point.

Acrylic Testing :

• 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.

General :

• 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.

How to Use Model 7.5 :

For tanning beds hold meter on bottom acrylic (bench) pointing up at closed canopy in center of bed for overall reading. Also can check individual lamps at acrylic to see if there are any reading much lower than the rest. In either case, allow lamps to warm up about 5 minutes to stabilize.

Model 7.5 : UV Radiometer

Virtuavia is the French Distributor for Solarmeter. 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. 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.
