Portable UV Light Meter UV Radiometers LCD Display UVA UVB Measure Tools UV340B UV Detector Spectrum 280nm-380nm Peak Value Hold Thanks for your purchase of our UV LIGHT METER , please read the following instructions carefully and always keep this manual within easy reach. UV light meter is with extremely precise structure. Once don’t use it, be sure to store it in the dry environment. We suggest you put the whole light meter including Desiccant into to the plastic bag and seal the bag as tightly as possible.  Please take the sensor out of the bag only when use it and replace the Desiccant periodically.  Comply to above method will extend the life of UV light meter. Otherwise, the gain of the UV sensor may be decreased and shorten the calibration period.     1.FEATURES:  *Professional, high quality UV light meter  *Measurable of UVA & UVB.  *UV detector spectrum from 280 nm to 380 nm.  *Three range selection switchable.  *Exclusive UV sensor structure.  *LSI-circuit use provides high reliability and durability  *Separate UV LIGHT sensor allows user to measure the UV light at an optimum position  *LCD display, easy readout.     2.APPLICATIONS:  Industrial:  *Monitoring blue light radiation hazards in welding  *UV sterilization  *Graphic arts  *Photochemical matching  *UV EPROM erasure  *Photoresist exposure  *Curing of inks, adhesives and coatings.     Laboratory:  *Weathering ‘degradation studies’  *UV sterilization  *Virology  *Microbial genetics  *DNA research  *Biologic hoods  *General laboratory use     3.SPECIFICATIONS:  *Display: 3 3/4 LCD display, maximum indication 3999  *Measurement ranges & resolution: 0-40 mW/cm2(3 Ranges),  400 μW/cm2 range  4000 μW/cm2 range  40 mW/cm2 range  (1000 μW/cm2 = 1 mW/cm2)  *UV sensor spectrum: Band pass 280 nm – 380 nm  *Accuracy: ±(4%FS + 2dgt)  FS: full scale ( Calibration is executed under the UVA light & and compare with the standard UVA light meter; Special tested under the environment RF Field Strength less than 3V/M & frequency less than the 30 MHz only)  *Sensor structure: The exclusive UV photo diode & UV color correction filter.  *Sample Time: Approx.  0.4 sec.   *Over Range indication:  indication of ‘OL’  *Operating Temperature & Humidity:   -10℃ to 40℃(32℉-104℉)  0～70%Rh  *Storage temperature-humidity:   -10℃ to 50℃(14℉-140℉)  0～80%Rh    *Power Supply: DC 9V battery, 006P, MN 1604 (PP3) or equivalent.(Not Included)  *Power Consumption: Approx.
