Specification
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.
