Hydrocyanic Acid Detection Tubes 0,5a (0.5 - 50 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

Hydrocyanic Acid Detection Tubes 0,5a (0.5 - 50 ppm)

Standard Measuring Range: 0.5 to 5 ppm 5 to 50 ppm
Number of Strokes (n): 10 2
Time for Measurement: approx. 2.5 min ca. 0.5 min
Standard Deviation: ±10 to 15 %
Color Change: yellow ─> red
Temperature: 0 to 40° C
Absolute Humidity: < 40 mg H2O / L
Reaction Principle: a) HCN + HgCl2 --> HCl
b) HCl + methyl red --> red reaction product
Cross Sensitivity: 30 ppm hydrogen sulfide, 300 ppm ammonia, 40 ppm sulfur dioxide, 20 ppm nitrogen dioxide and 1,000 ppm hydrogen chloride do not affect the indication.
Hydrogen sulfide causes the pre-layer to discolor to dark brown.
Ammonia concentrations above 300 ppm can cause the indication at the beginning of the indicating layer to discolor back to yellow.
Acylonitrile up to a concentration of 1,000 ppm does not affect the indication.
It is impossible to measure hydrocyanic acid in the presence of phosphine.
