The ORP sensor is a composite electrode composed of a glass indicator electrode and a reference electrode. The measurement of ORP is used to monitor ORP on the basis of the potential difference of the working battery and the linear relationship between the ORP value of the solution to be measured and the potential size of the working battery.

The ORP sensor is a composite electrode composed of a glass indicator electrode and a reference electrode. The measurement of ORP is used to monitor ORP on the basis of the potential difference of the working battery and the linear relationship between the ORP value of the solution to be measured and the potential size of the working battery.
functional characteristics:
Have good repeatability and stability;
Clean and reactivation is simple, and the balance speed is fast;
Optional analog-to-digital conversion module to realize digital signal output, strong anti-interference ability, long transmission distance;
Optional analog-to-digital conversion module to realize the standard digital signal output (RS485), which can be integrated and networked with other devices without a controller;
Sensor site installation is convenient and fast, using the terminal connection;
Simple use, reliable results, interface operation instructions can reduce operation errors;
Set up a visual alarm system to provide important alarm functions;
The controller can achieve wall mounting / panel mounting / clip mounting.
Typical applications:
ORP monitoring of tap water, municipal sewage, surface water and other industries;
ORP online monitoring of each process of water use and sewage and wastewater treatment in various industrial production processes.
