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
|Standard Measuring Range:
||1 to 10 ppm
||1 to 15 ppm
|Number of Strokes (n):
|Time for Measurement:
||approx. 1.5 min
||approx. 3 min
||blue ─> yellow
||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:
||max. 15 mg H2O / L
||HCl and/or HNO3 + pH indicator ──> yellow reaction product
||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.
