MFG: Draeger

Hydrogen Sulfide Detection Tubes 1/d (1 - 200 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 vapours can be detected and measured, e.g.: Determining and measuring concentration peaks, Measuring personal exposure in the inhalation area, Detecting leaks in pipelines, gas installations etc., and Air analysis in sewers, shafts and confined spaces.

Contains 10 tubes

Standard Measuring Range10 to 200 / 1 to 20 ppm
Number of strokes n:1 / 10
Time for Measurementapprox. 1 min. / approx. 10 min.
Standard Deviation± 15 %
Color Changewhite ──> brown
Temperature2 to 40°C
Absolute Humiditymax. 40 mg H2O / L
Reaction PrincipleH2S + Cu2 ──> CuS + 2H
Cross Sensitivity500 ppm hydrochloric acid, 500 ppm
sulfur dioxide, 500 ppm ammonia or
100 ppm asine do not interfere with the
reading. Methyl mercaptan and ethyl
mercaptan change the entire indicating
layer to a pale yellow. When mixed with
hydrogen sulfide, the reading is
extended by approx.30%
