Applications of SOLARMETER® 8.0 :

• Germicidal Lamp Intensity and Aging
• Eye Wear UV Block Comparison
• Germicidal Lamp Fixture Light Leak

Features and Benefits :

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

Sensor :

Silicon Diode (SiC) Photodiode in hermetically sealed UV glass window cap. Interference filter blocks UV above 280nm 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 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 :

• When checking UVC sources, wear face, hand, and eye protection and cover any skin that may be exposed.
• Allow lights to warm-up prior to taking readings (at least 5 min).
• For individual light intensity, hold meter close to LED or lamp.
• For effective light intensity, hold meter at working distance from the light source.
• When  checking  aging  of  lights,  keep  measuring  distance  and  locations constant.
• Lights should be replaced when output drops to about 70% of their original (new) readings.

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.
NOTE: Sensor is completely solar blind to UVB, UVA, visible and IR. Meter will read 000 pointing at non UVC sources including sun, flood lamps etc.

Ordering Information :

Model 8.0 : UVC 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!
