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 spot concentrations of specific gases. Measurement usually takes between 4 seconds and 15 minutes. The tubes are used either manually with the Draeger-Tube Accuro Pump or automatically with the Draeger X-act 5000.
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
Hydrochloric Acid/Nitric Acid Detection Tubes 1/a (1 - 10 ppm HCI)
| 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 |

|
| 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. |
