Signal analyzer W761-DCC1

waterchlorineprocess

The Inline Residual Chlorine Analyzer is equipped with a German-made CC1 sensor, which adopts a membrane-covered amperometric potentiostatic 3-electrode system with built-in electronics. It measures free chlorine, features automatic temperature compensation, requires no zero-point adjustment, and has highly reduced pH dependence. It is mainly applied to swimming pool water, drinking water, and sea water. In terms of technical characteristics, it offers good measurement stability, practical operation and maintenance, strong environmental adaptability, flexible signal and connection options, and complies with EMC and RoHS standards. Working Principle W761-DCC1 mainly consists of two parts: the control panel and the Germany-made CC1 free chlorine sensor specialized for swimming pool water. The controller displays the disinfectant value (main measured value), the pH value of the aqueous solution (a pH electrode is required for selection), and the working status. It outputs signals such as analog, digital, and switching signals. Application Swimming pool water, drinking water, sea water (partially tolerates surfactants, suitable for more complex water types than surfactant-intolerant models).
