REMOND Online UV254 Digital COD Sensor Probe RS485 Modbus COD Probe Sensor

Product Overview

The UV254 Optical Measurement Digital COD Sensor is an industrial-grade, online water quality monitoring probe designed for continuous measurement of Chemical Oxygen Demand (COD). It utilizes an advanced UV254 optical principle, which correlates organic content to UV absorption at 254 nm. This method offers stable, accurate, and reliable readings with the significant advantage of being less affected by sample turbidity and color compared to traditional methods. The sensor is digital, robust, and designed for low-maintenance operation in harsh environments.
