Application Range

Standard Measuring 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 š 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 š 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
