Mercaptan Detection Tubes 0.5/a (0.5 - 5 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

|Time for Measurement:

||± 10 to 15 %
||white ──> yellow
||10 to 40°C
||3 to 15 mg H2O / L
||2 R-SH + Pd2+ ──> Pd (RS)2 + 2 H+
||Higher molecular weight alkyl mercaptans (e.g. propyl- and butylmercaptans) are indicated with approximately the same sensitivity. 1,000 ppm ethylene, 2,000 ppm carbon monoxide and 200 ppm hydrogen sulfide do not affect the indication. Hydrogen sulfide discolors the pre-layer black.
