product key technologies
This industrial online ORP meter is used for real‑time monitoring of oxidation‑reduction potential (ORP) in water systems. It is widely applied in wastewater treatment, drinking water disinfection, electroplating, chemical processing, swimming pools, cooling water circulation and other industrial scenarios.
Equipped with a high‑sensitivity ORP electrode, the meter features stable signal output, strong anti‑interference capability, and long‑term reliable online operation. It supports continuous measurement, alarm output, analog transmission and digital communication, enabling automatic control of dosing systems and water treatment processes.
With a rugged industrial design, high and low temperature resistance, and easy installation and maintenance, it provides stable and accurate ORP data to ensure process safety and compliance with water quality standards.
