甲基環(huán)己醇CH3C6H10OH氣體檢測管199U METHYL CYCLOHEXANOL 5-200

簡要描述:

日本KITAGAWA北川式甲基環(huán)己醇CH3C6H10OH氣體檢測管199U METHYL CYCLOHEXANOL 5-200ppm,氣體檢測管的原理及使用,分析速度快。由于操作方便,使得每一次分析所需時間大為縮短,一般僅需幾十秒至幾分鐘即可得知結(jié)果,其分析速度是任何化學(xué)分析和儀器方法不能比擬的。適應(yīng)性好。檢測管現(xiàn)有Ⅰ、Ⅱ、Ⅲ三種,從零點到幾個PPM(10-6)到百分之幾十,適用范圍很大,為分析工作提供了很大方便。
