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 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:
||1 to 20 ppm
||0.17 L / min (CO2)
|Time for Measurement:
||± 15 %
||white ──> brown
||2 to 40°C
||max. 40 mg H2O / L
||The tube may only be used for depressurized compressed air
||H2S + Cu2+ ──> CuS + 2H+
||500 ppm hydrochloric acid, 500 ppm sulfur dioxide, 500 ppm ammonia or 100 ppm arsine do not affect the indication.
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 %.
