Mercaptan Detection Tubes 0.5/a (0.5 - 5 ppm)
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 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
Mercaptan Detection Tubes 0.5/a (0.5 - 5 ppm)
| Standard Measuring Range: |
0.5 to 5 ppm |
| Number of strokes n: |
20 |
| Time for Measurement: |
approx. 5 min |
| Standard Deviation: |
± 10 to 15 % |
| Color Change: |
white ??> yellow |
| Temperature: |
10 to 40°C |
| Absolute Humidity: |
3 to 15 mg H2O / L |
| Reaction Principle: |
2 R-SH + Pd2+ ??> Pd (RS)2 + 2 H+ |
| Cross Sensitivity: |
Higher molecular weight alkyl mercaptans (e.g. propyl- and butylmercaptans) are indicated with approximately the same sensitivity. 1,000 ppm ethylene, 2,000 ppm carbon monoxide and 200 ppm hydrogen sulfide do not affect the indication. Hydrogen sulfide discolors the pre-layer black. |
