Industrial Grade Ozone Controller and Monitor
MTWFCL5500 The Online pH Controller is a wall-mounted industrial intelligent instrument designed for continuous online monitoring and automatic control of pH and ORP in water. It features high-precision signal acquisition, intuitive LCD display, and user-friendly calibration menu for simple daily operation.
Built-in automatic temperature compensation ensures accurate measurement across variable water temperatures. It is equipped with relay control, 4-20mA analog output and RS485 MODBUS-RTU communication, supporting automatic dosing, alarm interlock and remote data transmission.
With IP65 front panel protection, strong anti-interference and stable performance, it adapts to harsh industrial environments for 24-hour uninterrupted operation.
Widely used in wastewater treatment, chemical production, aquaculture, circulating water, drinking water and environmental protection monitoring.
This Industrial Grade Ozone Controller and Monitor is a high-precision online water quality instrument,used for continuous real-time monitoring and automatic control of dissolved ozone in water. It matches industrial ozone sensor, supports automatic temperature compensation, with 4–20mA analog output, RS485 Modbus communication, relay alarm and linkage control. Stable, anti-corrosion and anti-interference design, suitable for water treatment, disinfection and industrial process monitoring.
Working Principle
Connect with industrial ozone sensor, adopt electrochemical measurement principle. Detect ozone concentration signal in real time, convert and calculate by the controller, realize data display, remote transmission and automatic control.
