Self-Cleaning Membraneless Digital Disinfectant Sensor
YG-CL20/DS
The self‑cleaning, membraneless digital disinfectant sensor is a proprietary three‑electrode amperometric sensor operating at constant potential, developed by our company, for measuring disinfectant concentrations such as free chlorine, chlorine dioxide (high‑purity), and ozone. The electrode integrates an ARM processor and an efficient filtering algorithm to effectively suppress noise, and features an RS‑485 interface for easy connection to computers and network monitoring systems.
