　　As it is well known,the ultraviolet rays can be widely applied to disinfection,physical treatment,detdctive discrimination and exposure optical carving etc. Otherwise,it can strongly damage something such as historical relic books and drawing,rubber products and plastics which will ba ageing after the radiation in the long time period. The ultraviolet rays is harmful to eyes,sin and rlowers etc. Model ZQJ-254 ultraviolet Intensity meter can measure the radiation dose of ultraviolet rays in the various enviroment.
#APPLICATIONS:
　　This meter can be widely applied to measure the radiation intensity of ultraviolet rays in the various enviroment. To the divisions which are engaged in biology, chemistry, medecine,sanitation, food, detective work, archaeology and to the factories of lamp production and glass production in which the ultraviolet transminssion rate of filter plate and quartz glass plate are measured meter is a necessary for often use purposes.
