Introduction

Principle & Structure

The ORP online analyzer is a composite electrode composed of a glass indicator electrode and a reference electrode. The measurement of ORP is based on the potential difference measured in the solution of the working battery composed of the measuring electrode and the reference electrode, and the linear relationship between the ORP value of the solution to be measured and the potential of the working battery is used to realize the online monitoring of ORP.

Features

● Simple cleaning and activation, and fast balancing;

● Visual alarm system;

● Sensor connection status display (online/offline);

● Built-in self-diagnosis function to ensure accurate data;

● The distance between the sensor and the transmitter can reach over 100 meters;

● Standard digital signal output;

● Modular installation of sensors to achieve plug and play;

● English and Chinese display can be switched, and the use of Chinese is more convenient;

application

Online monitoring of ORP in the process flow of sewage treatment plant inlet and outlet, sedimentation tank, biochemical reaction tank, etc.;

ORP monitoring in municipal water supply industry, surface water, aquaculture and other industries;

On-line monitoring of ORP for various industrial process water and wastewater treatment processes.
