Hydrochloric Acid Detection Tubes 0.2/a (0.2 - 20 ppm)
Short-Term Measurements with Draeger-Tubes
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.
Contains 10 tubes
|Standard Measuring Range||0.2 to 3 ppm / 3 to 20 ppm|
|Number of Strokes (n)||10 / 2|
|Time for Measurement||approx. 2 min. / 0.4 min.|
|Standard Deviation|| ±10 to 15 %|
|Colour Change||blue -> yellow|
|Temperature||5 to 40° C|
|Absolute Humidity||≤ 15 mg H2O / L|
|Reaction Principle||HCl + bomophenol blue ->|
yellow reaction product
|Cross Sensitivity||No interference on the reading of 10 ppm H2S |
and 2 ppm SO2. Other acid gases are also
indicated, however, with differing sensitivity.
Chlorine changes the indicating layer
to gray. If chlorine occurs simultaneously,
HCI readings will be higher.
