三氯乙烯Cl2C=CHCl气体测毒管134SB TRICHLOROETHYLENE 0.2-36.8ppm

1. PERFORMANCE
1） Measuring range ：1-16 ppm 0.2-3.2 ppm
Number of pump strokes 1（100ml） 4（400ml）
2） Sampling time ：1.5 minutes/1 pump stroke
3） Detectable limit ：0.1 ppm（400ml）
4） Shelf life ：1 year （Necessary to store in a refrigerated place ; 0～10℃）
5） Operating temperature ：0～40℃
6） Reading ：Direct reading from the scale calibrated by 1 pump stroke
7） Colour change ：Pale orange→Blueish purple
2. RELATIVE STANDARD DEVIATION
RSD-low：10％　RSD-mid.：10％　RSD-high：10％
3. CHEMICAL REACTION
By reacting with an Oxidizer, Hydrogen chloride is produced and PH indicator is discoloured.
CI2C＝CHCI＋PbO2＋H2SO4→HCI
