Mercaptan Detection Tubes 0.1/a (0/1 - 15 ppm)
For short-term measurements more than 160 Draeger Tubes are available to measure the so called spot concentrations of specific gases.
A wide range of different gases and vapors can be detected and measured, such as:
- Determining and measuring concentration peaks
- Measuring personal exposure in the inhalation area
- Detecting leaks in pipelines, gas installations etc.
- Air analysis in sewers, shafts and confined spaces
|Standard Measuring Range:
||0.1 to 2.5 ppm / 3 to 15 ppm
|Number of strokes n:
||10 / 2
|Time for Measurement:
||approx. 3 min / approx. 40 sec
||± 10 to 15 %
||yellow ──> pink
||5 to 40°C
||2 to 40 mg H2O / L
||2 R-SH + Hg Cl2 ──> Hg(CH3S)2 + 2 HCl
HCl + pH-indicator ──> reddish reaction
||Propyl mercaptan and n-butyl-mercaptan are indicated, but with different sensitivities. 4 ppm ethylene, 30 ppm CO, 10 ppm tetrahydrothiophene and 100 ppm hydrogen sulfide do not affect the indication. Hydrogen sulfide changes the pre-layer to black.
