Warning: Last items in stock!
Applications of SOLARMETER® 6.4 :
• Vitamin D Dose in IU/min
• Lamp Intensity in Terms of Vitamin D Production
• Solar Intensity in Terms of Vitamin D Production
Features and Benefits of SOLARMETER® 6.4 :
• Hand Held Integral Sensor
• Accurate Calibration
• NIST Traceable
• Compact and Durable
• LCD Readout
Silicon Carbide (SiC) Photodiode packaged in hermetically sealed UV Glass window cap. Interference filter blocks most non-erythema (non-D3) irradiance from 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 the sun or UV lamp source.
Press and hold the push-button switch on the face of the meter. Reading represents IU/min D3 on 10% body surface.
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® D3 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).
• Keep track of exactly how long you are exposed to a UV source to properly calculate total vitamin D produced.
• 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.

Some helpful formulas embedded in the utility found at www.solarmeter.fr.
• 1000 IU = 1 MED (Minimal Erythemal Dose) The minimum dose of radiation that produces a sunburn.
• 1 IU/min = 1/1000 MED/min (or 0.06 MED/hr, which = 1/16.67 MED/hr)
• 1 MED/hr = 2.33 UVI and 1 MED/hr = 16.67 IU/min.
• The conversion constant for IU/min to UVI is 16.67 / 2.33 = 7.1 UVI.

Model 6.4 : D3 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!
