Residual chlorine water quality online monitor
Model：ERUN-SZ1-A-K6
Residual chlorine (polarographic method)
Residual chlorine detector is an on-line intelligent residual chlorine monitor produced by our company, which adopts imported components and permeation membrane head, based on polarographic analysis technology and advanced production process and surface paste technology. Using this series of advanced analyzing technology, it ensures the stable reliability and accuracy of the instrument for long-term work. With Chinese/English menu operation, notepad storage of measurement data, 485 communication and other functions. Widely used in circulating water self-control dosing, swimming pool chlorination control as well as drinking water treatment plant, drinking water distribution network, swimming pools, hospital wastewater, water quality treatment works, etc. for continuous monitoring and control of residual chlorine content in water solution.
