氯乙烯氣體檢測管132SC VINYL CHLORIDE 1-22ppm

Tube 32SC
1. PERFORMANCE
1） Measuring range ：0.4-12.0 ppm 0.2-6.0 ppm 0.1-3.0 ppm
Number of pump strokes 1（100ml） 2（200ml） 4（400ml）
2） Sampling time ：3 minutes/2 pump strokes
3） Detectable limit ：0.05 ppm（400ml）
4） Shelf life ：3 years
5） Operating temperature ：0～40℃
6） Temperature compensation ：Necessary（0～15℃）（See "TEMPERATURE CORRECTION TABLE"）
7） Reading ：Direct reading from the scale calibrated by 2 pump strokes
8） Colour change ：Greenish yellow→Pink
2. RELATIVE STANDARD DEVIATION
RSD-low：10％　RSD-mid.：10％　RSD-high：10％
3. CHEMICAL REACTION
By decomposing with an Oxidizer, Hydrogen chlorine is produced and PH indicator is discoloured.
CH2＝CHCI＋CrO3＋H2SO4→HCI
