Membrane-Covered Digital Disinfectant Sensor
YG-CM/DPM（Original Model：YG-CL20/DPM）
The YG‑CL20/DP membrane‑less digital disinfectant sensor is a three‑electrode potentiostatic amperometric sensor developed in‑house. It measures disinfectant concentrations such as free chlorine, chlorine dioxide (high‑purity), and ozone, and is mainly used for treated water at plant outlets, distribution networks, secondary water supply, tap water, swimming pools, and similar applications. The electrode integrates an ARM processor and efficient filtering algorithms to suppress noise. RS‑485 and 4–20 mA outputs make it easy to connect to computers and SCADA/monitoring systems.
