Intelligent Inline Free Chlorine Analyzer with CC1 Sensor for Swimming Pool Water
In terms of technical characteristics, it offers good measurement stability, practical operation and maintenance, strong environmental adaptability, flexible signal and connection option, 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).
