Digital Dissolved Oxygen Sensor YG-FD
詳細仕様は英語で表示されます。
The digital dissolved oxygen sensor is a digital sensor developed by YuanGan for online drinking-water quality monitoring, with the digital circuit integrated inside the sensor. It monitors two parameters in real time: dissolved oxygen concentration and temperature, using an RS-485 interface and the Modbus-RTU communication protocol. It is widely used for online dissolved oxygen monitoring of domestic drinking water, surface water, groundwater, wastewater and more.
Typical applications
- Domestic Drinking Water
- Surface Water
- Groundwater
- Online dissolved oxygen monitoring of wastewater and more
