MFG: Draeger

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 Range0.2 to 3 ppm / 3 to 20 ppm
Number of Strokes (n)10 / 2
Time for Measurementapprox. 2 min. / 0.4 min.
Standard Deviation ±10 to 15 %
Colour Changeblue -> yellow
Temperature5 to 40° C
Absolute Humidity≤ 15 mg H2O / L
Reaction PrincipleHCl + bomophenol blue ->
yellow reaction product
Cross SensitivityNo 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.
