氯乙烯CH2=CHCl气体检知管132SB VINYL CHLORIDE 5-500ppm
Tube 32SB
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

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.
CH2=CHCI+PbO2→CI2
