氯乙烯氣體檢測(cè)管132SC VINYL CHLORIDE 1-50ppm

簡(jiǎn)要描述:

o-Chlorotoluene ClC6H4CH3 132SC VINYL CHLORIDE (-) 1-50ppm 氯乙烯氣體檢測(cè)管,鄰氯甲苯測(cè)毒管,2-氯甲苯檢測(cè)管,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(shí),人們就感覺(jué)到,因此,世界上使用臭氧已有一百多年的歷史,至今也沒(méi)有發(fā)現(xiàn)一例因臭氧中毒而導(dǎo)致死亡的報(bào)道。
