【Description】

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.
