Toluene Detection Tubes 100/a (100 - 1800 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
