                      丙酮?dú)怏w檢測管102SD ACETONE 20-200ppm

                      簡要描述:

                      丙酮?dú)怏w檢測管102SD ACETONE (-) p-Cymene CH3C6H4CH(CH3)2 20-200ppm,環(huán)境監(jiān)測站近日從我公司購入一套惡臭氣體應(yīng)急檢測箱,用于檢測各種場合大氣中的惡臭氣體和臭氣濃度。這一儀器將替代國標(biāo)“三點(diǎn)式臭袋法",其檢測效果等同于“三點(diǎn)式臭袋法",而檢測效率將獲明顯提升。
