Hydrazine Detection Tubes 0.01/a (0.01 - 6 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 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.

(Standard Deviation ±50 %) 5 ppm Ammonia at
100 strokes result in a measurement of approx.
0.01 ppm Hydrazine. At 5 strokes, Ammonia
will also not be shown in high concentrations.
|* Number of strokes is printed on the tube. As a result of manufacturing
of processes the number of strokes can vary between 100 to 150
strokes for the low measuring range.
