                      氯乙烯CH2=CHCl氣體檢知管132SB VINYL CHLORIDE 5-500ppm

                      簡(jiǎn)要描述:

                      氯乙烯CH2=CHCl氣體檢知管132SB VINYL CHLORIDE 5-500ppm,其它有害作用: 氯乙烯在環(huán)境中能參與光化學(xué)煙霧反應(yīng),由于其揮發(fā)性強(qiáng),在大氣中易被光解,也可被生物降解和化學(xué)降解,即能被特異的菌叢所破壞,亦能被空氣中的氧所氧化成苯甲醚、甲醛及少量苯乙醇。

                      1. PERFORMANCE
                      1) Measuring range :5-500 ppm
                      Number of pump strokes 1(100ml)
                      2) Sampling time :1.5 minutes/1 pump stroke
                      3) Detectable limit :2 ppm
                      4) Shelf life :1.5 years(Necessary to store in a refrigerated place ; 0~10℃)
                      5) Operating temperature :0~40℃
                      6) Temperature compensation :Necessary(See "TEMPERATURE CORRECTION TABLE")
                      7) Reading :Direct reading from the scale calibrated by 1 pump stroke
                      8) Colour change :White→Reddish orange
                      2. RELATIVE STANDARD DEVIATION
                      RSD-low:15% RSD-mid.:10% RSD-high:10%
                      3. CHEMICAL REACTION
                      By decomposing with an Oxidizer, Chlorine is produced. This Chlorine reacts with o-Toluidine and red
                      Orthoquinone is produced.
