The S-RC051 membrane-free digital disinfectant sensor is a three-electrode constant potential current measurement sensor developed by our company with independent intellectual property rights. It can be used to measure the concentration of disinfectants such as residual gas, high-purity chlorine dioxide, and ozone. The electrodes have a built-in ARM processor and a high-efficiency filtering algorithm, which can effectively avoid noise interference.

· Electrochemical sensor with no reagent consumption or pollutant discharge
· Membrane-covered design prevents contamination and failure of the working electrode
· Accurate comparison with DPD measurement method
· Membrane-free design eliminates the need for membrane replacement and electrolyte addition
· Three-electrode design ensures stable zero point and high sensitivity
