1,1-二氯乙烷CH3CHCl2气体检测管 235SA 1,1- 10-160ppm

简要描述:

1,1-二氯乙烷CH3CHCl2气体检测管 235SA 1,1- 10-160ppm 乙叉二氯,1,1-Dichloroethane,使用时将管子两端割断,让含有被测物质的气体定量地通过管子,被测物质即和管中检测剂发生定量化学反应,部分检测剂被染色,其染色长度与被测物浓度成正比,从检测管上已印制好的刻度即得知被测气体的浓度。

Tube No.235SA

1. PERFORMANCE
1) Measuring range :10-160 ppm
Number of pump strokes 1(100mr)
2) Sampling time :2 minutes/1 pump stroke
3) Detectable limit :3 ppm
4) Shelf life :1 year(Necessary to store in a refrigerated place ; 0~10℃)
5) Operating temperature :0~40℃
6) Operating Humidity :20-90 R.H.%
7) Temperature compensation :Necessary(See "TEMPERATURE CORRECTION TABLE")
8) Reading :Direct reading from the scale calibrated by 1 pump stroke

2. RELATIVE STANDARD DEVIATION
RSD-low:15% RSD-mid.:15% RSD-high:10%
3. CHEMICAL REACTION
Chlorine is produced by decomposing with an Oxidizer.
By reacting between this Chlorine and 3, 3’-Dimethylnaphthidine,Nitroso-compound is produced.
CH3CHCI2+CrO3+H2SO4→CI2
CI2+3, 3’-Dimethylnaphthidine→Nitroso-compound
