Application Range
Standard Measuring Range: 20 to 40 mg/L / 1 to 18 mg/L
Number of Strokes n: 1 / 2
Time for Measurement: approx. 20 s / approx. 40 s
Standard Deviation: ± 15 to 20 %
Color Change: yellow -> turquoise-blue
Ambient Operating Conditions
Temperature: 0 to 50 °C
Absolute Humidity: up to 100% r.h.
Condensation in the tube causes measurement errors. If high r.h. (in excess of 80%) is to be expected, the temperature of the tube should be at least 5 °C higher than ambient temperature.Given a r.h. below 80%, the temperature of the tube should be at least equal to the ambient temperature.
Reaction Principle
H2O + Mg(CIO4)2 -> turquoise-blue reaction product
Cross Sensitivity
Acid gases are liable to cause plus errors. Basic gases are liable to cause minus errors.
