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.
