pH / ORP Sensors

Digital Combined pH/ORP Sensor YG-DX/01

YG-DX/01Former model: YG-OPS/D21

詳細仕様は英語で表示されます。

The all-in-one pH/ORP sensor is a digital sensor developed by YuanGan for online drinking-water quality monitoring, with the digital circuit integrated inside the sensor. It monitors three parameters in real time: pH, ORP and temperature, using an RS-485 interface and the Modbus-RTU communication protocol.

Typical applications

Water Treatment Plants
Secondary Water Supply
Network-End (Tap) Water
Direct Drinking Water
Membrane-Filtered Water
Swimming Pools
Online turbidity monitoring of surface water and more
