MTW-ACC100 Ozone O3 Sensor is a special electrochemical probe for real-time continuous measurement of dissolved ozone (O3) in water. It adopts exclusive anti-oxidation sensing diaphragm and electrode core, effectively avoiding oxidation damage and aging caused by ozone medium, greatly extending service life.

Built-in Pt1000 temperature compensation component eliminates measurement deviation caused by water temperature fluctuation, ensuring stable and consistent detection data. It supports standard RS485 MODBUS-RTU digital communication, which can be matched with ozone controllers, PLC, data acquisition terminals and cloud monitoring platforms directly.

The whole body adopts fully sealed corrosion-resistant structure with IP68 waterproof grade, supporting submerged installation and flow cell installation. Fast response speed, low signal drift and simple daily cleaning maintenance, suitable for 24-hour long-term online operation.

It is widely used in ultrapure water system, swimming pool ozone disinfection, beverage and food production water, sewage advanced oxidation treatment and municipal water disinfection projects.

This Ozone O3 Sensor is a digital online probe for detecting dissolved ozone concentration in water. It uses stable electrochemical sensing chip, equipped with anti-oxidation electrode to resist long-term erosion of ozone liquid. Built-in automatic temperature compensation to avoid measurement error caused by temperature fluctuation.

Standard RS485 Modbus-RTU digital signal output, can be directly connected to ozone controller, PLC and cloud monitoring system without extra signal converter. IP68 fully waterproof submersible structure, 3/4" NPT standard thread for pipeline, tank and bypass installation. Multiple measuring ranges optional, low drift, high repeatability, low maintenance for continuous 24/7 operation.
