Specification Use Hight quality 311nm special UV lamp as light source, with best stability and long life Small size, light weight, patients can take with themselves; hand-held operation; Reasonable price, use simply, patients can bring and cure at home. Unique comb design, can take the treatment of scalp; Additional reflectors designed to improve the radiation efficiency; Unique anti-jamming technology to ensure that the equipment in strong magnetic field may be a normal work; Blue LCD display, coupled with microcomputer timer function, ensure the accuracy of treatment time. ( be applicable to products with LCD control circuit ) Feacture Working voltage:AC120V 60Hz, AC 22010%,50Hz2% or AC 230V10%,50Hz2%(the products voltage which export to EU region is AC 230V10% 50Hz2%,the rest place work voltage see product nameplate). Power rating: 50VA Fuse protector: T0.5AL/25OV 3.6x 10 Woring Cntienin Temprature 5- 40; Relative humidity; 85%; Atmospheric pressure: 700hPa 1060hPa Structure: handheld Work distance: 3cm0.5cm Effective Radiant area: 55cm10% Timing: The device has a timer, the timing error within 2% range. Note: the max. radiating intensity is the defined intensily of this prodtuct. This is expressed in terms of miliwatts per square centimeter of surfacc area. The UV lamp's intensity will reduce during the aging of lamp, so please make use of the device in the inensity range listed in the table above to ensure the effectiveness of treatment.
