Request a QuoteProduct Overview
The TL-O3-201 uses constant voltage amperometric method to measure dissolved ozone concentration in water. Used for ozone disinfection system control in drinking water treatment, bottled water production, and aquaculture.
Working Principle
Electrochemical sensors measure ion activity or electrical properties of the liquid. A reference electrode and measuring electrode create a potential difference proportional to the ion concentration (pH/ORP), or an AC excitation signal is applied across electrodes to measure conductivity. Built-in NTC temperature compensation corrects readings across the full operating temperature range. RS485 Modbus RTU output transmits calibrated values directly to PLCs and SCADA systems.
