正丙基硫醇CH3CH2CH2SH檢測(cè)管130U n-PROPYL MERCAPTAN 0.5-10ppm

1. PERFORMANCE
1） Measuring range ：1-10 ppm 0.5-5 ppm
Number of pump strokes 1/2（50ml） 1（100ml）
2） Sampling time ：1 minute/1 pump stroke
3） Detectable limit ：0.2 ppm（100ml）
4） Shelf life ：2 years
5） Operating temperature ：0～40℃
6） Reading ：Direct reading from the scale calibrated by Methyl mercaptan at 1 pump stroke
7） Colour change ：Pale yellow→Pink
2. RELATIVE STANDARD DEVIATION
RSD-low：10％　RSD-mid.：5％　RSD-high：5％
3.CHEMICAL REACTION
By reacting with Mercuric chloride, Hydrogen chloride is produced and PH indicator is discoloured.
（CH3）3CSH＋HgCI2→（CH3）3CS（HgCI）＋HCI
