Draeger Tube - Hydrochloric Acid / Nitric Acid 1/a
Order No. 81 01 681
|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|
|HCI 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 effect the reading. Chlorine concentrations in excess of 1 ppm change the entire indicating layer to a yellow-green.|
