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, 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

Number of strokes n: 2
Time for Measurement: approx. 30 sec
Standard Deviation: ± 10 to 15 %
Color Change: gray ──> red brown
Temperature: 15 to 40 °C

Reaction Principle: a) NO + CrVI ──> NO2
b) NO2 + o-dianisidine ──> red brown reaction product
Cross Sensitivity: There is no influence of chlorine and ozone, if these gases are in range of their TLVs. Higher concentrations are indicated with different sensitivities.
