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 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:
||0.01 to 0.4 ppm / 0.5 to 6 ppm
|Number of Strokes (n):
||see tube* / 5
|Time for Measurement:
||approx. 20 to 30 min / approx. 1 min
||±20 to 25 %
||pale gray ─> gray-brown
||10 to 30° C
||1 to 20 mg H2O / L

||1.1-Dimethylhydrazin and Monomethylhydrazine are shown with the same sensitivity (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
|* 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.
