The measuring range is defined by the reagent used. The entire
measuring range of the total hardness is achieved by using different
reagents.
Measurement accuracy:
+/- 5% of the upper value of the respective reagent (see page 74.)
Repetition accuracy:
+/- 2.5% of the upper value of the respective.
Please note: The accuracy of the measurements may be adversely affected
by the impurity of the water. In such cases, we recommend that you take a
hardness measurement by hand titration and then calibrate the analysis
unit to this value.
ca. 0.05-0.5 ml/ analysis depending on the hardness of the water
ca. 3 minutes depending on the hardness of the water
ca. 10,000 analyses / 500 ml reagent by low hardness. The consumption is
dependent on the measured water hardness and the reagent used.
At least 2 years
ca. 1l/analysis at 2 bar
The water consumption varies according to pressure and flush-time.
