Hydrochloric Acid/Nitric Acid Detection Tubes 1/a (1 - 10 ppm HCI)

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
Substance: Hydrochloric Acid Nitric Acid
Standard Measuring Range: 1 to 10 ppm 1 to 15 ppm
Number of Strokes (n): 10 20
Time for Measurement: approx. 1.5 min approx. 3 min
Standard Deviation: ±30 %
Color Change: blue ─> yellow
Temperature: 5 to 40° C for HCl

For HNO3 measurements, the tube scales are applicable only to 20° C. Where the temperature is different, the measuring result must be multiplied as follows:

Temperature °C Factor
40 0.3
30 0.4
10 2
Absolute Humidity: max. 15 mg H2O / L
Reaction Principle: HCl and/or HNO3 + pH indicator ──> yellow reaction product
Cross Sensitivity: 50 ppm nitrogen dioxide result in almost the same reading as 2 ppm nitric acid. 10 ppm hydrogen sulfide or 5 ppm nitrogen dioxide do not affect the reading. Chlorine concentrations in excess of 1 ppm change the entire indicating layer to a yellow-green.
