Water Vapor Detection Tubes 1/b (1 - 40 mg/l)

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: 20 to 40 mg/L / 1 to 18 mg/L
Number of Strokes (n): 1 / 2
Time for Measurement: approx. 20 sec. / approx. 40 sec.
Standard Deviation: ± 15 to 20 %
Color Change: yellow ──> turquoise-blue
Temperature: 0 to 50° C
Absolute Humidity: up to 100% r.h.
Condensation in the tube causes measurement errors. If high r.h. (in excess of 80%) is to be expected, the temperature of the tube should be at least 5 °C higher than ambient temperature. Given a r.h. below 80%, the temperature of the tube should be at least equal to the ambient temperature.
Reaction Principle: H2O + Mg(ClO4)2 ──> turquoise-blue reaction product
Cross Sensitivity: Acid gases are liable to cause plus errors. Basic gases are liable to cause minus errors.
