Aniline Detection Tubes 5/a (1 - 20 ppm)
Drager 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 Drager-Tubes are available to measure the so-called spot concentrations of specific gases. Measurement usually takes between 4 seconds and 15 minutes. The tubes are used either manually with the Drager-Tube pump accuro or automatically with the Drager X-act 5000.
A wide range of different gases and vapours can be detected and measured, e.g.: Determining and measuring concentration peaks, Measuring personal exposure in the inhalation area, Detecting leaks in pipelines, gas installations etc., and Air analysis in sewers, shafts and confined spaces.

Ammonia concentrations up to 50 ppm do
not affect the indication, higher ammonia
concentrations will cause plus errors.

reagent ampoule must be broken. The
granular contents must be shaken out of
the ampoule by tapping the side of the tube.
During the measurement. the Drager-Tube
must be held vertically with the inlet of the
