Overview

The Lumin-S Optical Dissolved Oxygen Sensor with Digital Communication is a smart optical dissolved oxygen (DO) sensor designed for accurate and reliable measurement in water and wastewater applications. It uses luminescence-based optical technology to deliver stable readings without drift or dependency on flow conditions.

Unlike traditional electrochemical sensors, it requires minimal maintenance since it has no membranes, electrolytes, or anodes. The sensor features built-in digital communication (Modbus/RS-485), enabling direct integration with PLC systems for industrial automation.
