COD Sensors

The SensorsX SX-CHUCA Series is a self-cleaning UV254 sensor designed for continuous COD, TOC, turbidity, and temperature monitoring in water. Using a reagent-free UV absorption method, it features automatic turbidity compensation and an integrated cleaning brush for stable, low-maintenance operation. With RS-485/Modbus communication and IP68 protection, it is ideal for wastewater treatment, industrial effluent, and surface water monitoring.
