Product Introduction
The HXOP-500 ORP sensor is a composite electrode composed of a noble metal indicator electrode and a reference electrode. The measurement of ORP is based on the potential difference measured by the working battery composed of the measuring electrode and the reference electrode in the solution, and the linear relationship between the ORP value of the test solution and the potential of the working battery is used to achieve online monitoring of ORP.
Product Features
Has good repeatability and stability;
Cleaning and activation are simple, and the balance speed is fast;
Optional analog-to-digital conversion module for digital signal output, strong anti-interference ability, and long transmission distance;
Optional analog-to-digital conversion module can be used to achieve standard digital signal output (RS485), which can be integrated and networked with other devices without a controller;
The on-site installation of sensors is convenient and fast, using terminal connections.
Typical applications
ORP monitoring of industries such as tap water, municipal sewage, and surface water;
Online monitoring of ORP for water and wastewater treatment processes in various industrial production processes.
