- Working principle of the analyzer is the titration of a water
sample with hydrochloric acid to determine the KS4.3 value(+m-value).
A second reagent (indicator) is dosed for the photometric detection
of the color change, the display is touchscreen.External start/stop
of an analysis possible.
User can set the start value and end value.
Mannual calibration.
Application for the analyzer is power plant,thermal power plant,chemical plant and so on.
