Nitrogen Dioxide Detection Tubes 2/c (2 - 100 ppm)
For short-term measurements more than 160 Draeger Tubes are available to measure the so called spot concentrations of specific gases.
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
|Standard Measuring Range:
||5 to 100 ppm / 2 to 50 ppm
|Number of strokes n:
||5 / 10
|Time for Measurement:
||approx. 1 min / approx. 2 min
