Digital Disinfectant Sensor YG-CD (Membraneless)

YG-CDFormer model: YG-CL20/DS

詳細仕様は英語で表示されます。

The membraneless digital disinfectant sensor is a three-electrode potentiostatic amperometric sensor developed by YuanGan with proprietary intellectual property. It measures disinfectant concentrations such as free chlorine, chlorine dioxide (high-purity) and ozone. An ARM processor and efficient filtering algorithm built into the electrode effectively suppress noise, and the RS-485 interface makes it easy to connect to computers and network monitoring systems.

Typical applications

Water Treatment Plants
Secondary Water Supply
Swimming Pools
Water Transmission Network
