Hydrogen Sulfide Detection Tubes 0.2%/A (0.2 - 7% vol)

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 vapours 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: 0.2 to 7 Vol. %
Number of Strokes (n): 1 + 2 desorption strokes in clean air
Time for Measurement: approx. 2 min
Standard Deviation: ±5 to 10 %
Color Change: pale blue ──> black
Temperature: 0 to 60° C
Absolute Humidity: max 40 mg H2O / L
Reaction Principle: H2S + Cu2+ ──> CuS + 2 H+
Cross Sensitivity: In the presence of sulfur dioxide, the indicating layer can change to a yellowish color, but the hydrogen sulfide measurement is not affected. Comparable concentrations of mercaptan will interfere with the reading.
