Phosphine Detection Tubes 0.01/a (0.01 - 1.0 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: 0.1 to 1.0 ppm / 0.01 to 0.3 ppm
Number of strokes n: 3 / 10
Time for Measurement: approx. 2.5 min / approx. 8 min
Standard Deviation: ± 10 to 15 %
Color Change: yellow ──> red
Temperature: 2 to 40 °C
Absolute Humidity: < 20 mg H2O / L
Reaction Principle: PH3 + HgCl2 ──> HCl + Hg-Phosphide
HCl + pH Indicator ──> red reaction product
Cross Sensitivity: Arsine is indicated with different sensitivity. Up to 6 ppm sulfur dioxide or 15 ppm hydrochloric acid does not interfere, but higher concentrations cause plus errors. More than 100 ppm ammonia leads to minus errors. 30 ppm hydrocyanic acid does not affect the 3 stroke test, but with the 10 stroke test minus errors of up to 50 % can occur.
