Water Vapor Detection Tubes for Aerotest 20/a-P (20 - 1500 mg H20/m3)
Draeger Short-term Tubes have proven to be a very cost-effective and reliable method for the measurement of gases.
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 with the Draeger-Tube Accuro Pump.
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
