COD Sensor

Description

The COD (Chemical Oxygen Demand) Sensor enables real-time monitoring of organic pollutants in water using UV absorption technology. It provides fast, accurate measurements without the need for chemical reagents, significantly reducing maintenance and operational costs. With integrated automatic cleaning and MODBUS RTU output, it is ideal for continuous operation in demanding water quality applications.
