Digital Disinfectant Sensor YG-CP (Membraneless)
상세 사양은 영어로 표시됩니다.
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, and is mainly used in treated water at the plant outlet, distribution networks, secondary water supply, network ends and swimming pools. An ARM processor and efficient filtering algorithm built into the electrode effectively suppress noise, and RS485 and 4–20 mA outputs make it easy to connect to computers and network monitoring systems.
Typical applications
- Water Treatment Plants
- Distribution Network
- Secondary Water Supply
- End Users
- Swimming Pool Water
- Other Water Treatment Equipment
