Single-Parameter Analyzers

ORP Online Analyzer YG-NHR/01

YG-NHR/01Former model: YG-UK/KA

The ORP online analyzer is a product independently developed by YuanGan for online water quality monitoring. A universal controller works together with an ORP sensor to continuously monitor ORP in the solution. The data can be sent to a recorder through the transmitter output for remote monitoring and logging, or connected to a computer through the RS485 interface using the Modbus-RTU protocol, so the computer can monitor and record the instrument.

Typical applications

Water Treatment Plants
Distribution Network
Secondary Water Supply
