日本理化臭氧O3氣體檢測管182U
日本理化臭氧O3氣體檢測管182U ,臭氧O3氣體測毒管182U OZONE 0.025-3.0ppm,日本光明理化工業(yè)株式會社從1947年開始,在氣體分析領(lǐng)域開拓了六十余年 , 形成了馳名于世的 ” 北川 ” 式氣體檢測管。氣體快速分析法 ” 北川 ” 的歷史就是日本檢測管的歷史 。目前是世界上*大的檢測管生產(chǎn)廠家,也是日本**家通過美國SEI的認證,歐盟的認證的檢測管廠家。公司不僅有ISO9001:2000的認證,還獲得了環(huán)境管理的ISO14001的認證。北川式手動氣體采集器AP-20 備有采氣完成指示計 , 可以清楚的判明采氣是否完成 . • 有專門截留玻璃的截留槽 , 以防止檢測管割尖時玻璃片飛濺 . • 有采氣容積為 50 毫升和 100 毫升的兩段式制動卡 . • 采氣器極為小巧 , 并有便于攜帶的皮具包 。
臭氧屬于有害氣體,濃度為 6.25×10mol/L(0.3mg/m3 ) 時,對眼、鼻、喉有刺激的感覺;濃度 (6.25-62.5)×10 -5 mol/L(3 ~ 30mg/m3 ) 時,出現(xiàn)頭疼及呼吸器官局部麻痹等癥 ; 臭氧濃度為 3.125×10 -4 ~ 1.25×10 -3 mol/L(15 ~ 60mg/m 3 ) 時 , 則對人體有危害。其毒性還和接觸時間有關(guān),例如長期接觸 1.748×10 -7 mol/L(4ppm) 以下的臭氧會引起長久性心臟障礙,但接觸 20ppm 以下的臭氧不超過 2h ,對人體無長久性危害。因此,臭氧濃度的允許值定為 4.46×10 -9 mol/L(0.1ppm)8h. 由于臭氧的臭味很濃,濃度為 4.46×10 -9 mol/L(0.1ppm) 時,人們就感覺到,因此,世界上使用臭氧已有一百多年的歷史,至今也沒有發(fā)現(xiàn)一例因臭氧中毒而導致死亡的報道。
