ZQJ-254型紫外輻射照度計

    紫外線的應用很廣泛，如紫外線殺菌消毒，紫外線理療，紫外線熒光分析和鑒別偵破，紫外線曝光光刻等。紫外線的破壞作用在某些場合是非常危險的。如文物書畫，橡膠塑料，在長期照射下會發生老化，紫外線還會傷害眼睛，皮膚和花木等等。ZQJ-254紫外輻射照度計測儀能測量各種環境中的紫外線輻照劑量。

一、ZQJ-254型用途

可廣泛適用于測量各種場合的紫外輻射強度,對從事生物、化學、醫療、衛生、食品、偵破、考古部門和對測量濾色片及石英玻璃片的紫外線透過率，是生產燈泡和玻璃制品廠等單位的*的檢測儀器。

　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.
