1,3-二氯丙烷氣體檢測管194S 1,3-DICHLOROPROPANE 10-500ppm

Tube No.
194S
1. PERFORMANCE
1） Measuring range ：10-500 ppm
Number of pump strokes 1（100ml）
2） Sampling time ：1.5 minutes/1 pump stroke
3） Detectable limit ：1 ppm
4） Shelf life ：1 year （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→Orange
2. RELATIVE STANDARD DEVIATION
RSD-low：15％　RSD-mid.：15％　RSD-high：10％
3. CHEMICAL REACTION
By decomposing with an Oxidizer, chlorine is produced. Yellowish Orthoquinone is produced by reacting
between this Chlorine and o-Toulidine.
CH2CICH2CH2CI＋I2O4＋CrO3＋H2SO4→CI2
