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 spot concentrations of specific gases. Measurement usually takes between 4 seconds and 15 minutes. The tubes are used either manually with the Draeger-Tube Accuro Pump or automatically with the Draeger X-act 5000.
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
Hydrogen Sulfide Detection Tubes 0.2%/A (0.2 - 7% vol)
| 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 |
