Hydrogen Sulfide 0.2/b (0.2 - 6 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 Range0.2 to 6 ppm
Number of strokes n:1
Time for Measurementapprox. 55 sec.
Standard Deviation± 15 to 20 %
Color Changeyellow ──> pink
Temperature15 to 40°C

In case of temperature between 0°C
and 10°C, the reading has to be
multiplied by 1.5;
Standard deviation ±30%
Absolute Humiditymax. 20 mg H2O / L
Reaction PrincipleH2S + HgCl2 ──> HgS + 2HCl
HCL + pH indicator ──> pink reaction
Cross SensitivityUp to 1000 ppm, sulfur dioxide has no
influence on the reading. Within the
range of their TLV, mercaptanes,
arsine, phosphine and nitrogen dioxide
are also indicated, however, with
differing sensitivity. Within its TLV,
hydrogen cyanide changes the color of
the entire indicating layer to a light
orange. The reading of hydrogen
sulfide is not affected.
