Details
Draeger Tube - Hydrochloric Acid / Nitric Acid 1/a
Order No. 81 01 681
| Application Range | |
| Standard Measuring Range | Hydrochloric acid: 1 to 10 ppm Nitric acid: 1 to 15 ppm |
| Number of Strokes n: | Hydrochloric acid: 10 Nitric acid: 20 |
| Time for Measurement: | Hydrochloric acid: approx. 1.5 min. Nitric acid: approx. 3 min. |
| Standard Deviation: | ± 30% |
| Color Change: | blue to yellow |
| Ambient Operating Conditions | |
| Temperature: | 5 to 40° C ~ 41 to 104° F |
| 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 40° C = Factor: 0.3 Temperature 30° C = Factor 0.4 Temperature 10° C = Factor 2 |
|
| Absolute Humidity: | max. 15 mg H2O / L |
| Reaction Principle | |
| HCI 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 effect the reading. Chlorine concentrations in excess of 1 ppm change the entire indicating layer to a yellow-green. | |
