Trichloroethylene Detection Tubes 2/a (2 - 250 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

approx. 1.5 min / 2.5 min |
| Standard Deviation: |
± 10 to 15 % |
| Color Change: |
pale gray ??> orange |
| Temperature: |
10 to 40 °C |
| Absolute Humidity |
5 to 15 mg H2O / L |
| Reaction Principle: |
