- Can be used as pre-entry checks
Application Range | ||
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 | |
Ambient Operating Conditions | ||
Temperature: | 5 to 40 °C for HCI | |
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 effect the reading. Chlorine concentrations in excess of 1 ppm change the entire indicating layer to a yellow-green. | ||
