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
Standard Measuring Range: 0.5 to 5 ppm
Number of strokes n: 20
Time for Measurement: approx. 5 min
Standard Deviation: ± 10 to 15 %
Color Change: white ──> yellow
Temperature: 10 to 40°C
Absolute Humidity: 3 to 15 mg H2O / L
Reaction Principle: 2 R-SH + Pd2+ ──> Pd (RS)2 + 2 H+
Cross Sensitivity: 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.
