产品概述
• SS306-01-N01 measures chemical oxygen demand (COD) using dual-wavelength ultraviolet absorption without chemical reagents.
• The integrated self-cleaning system reduces biofouling, with automatic temperature and turbidity compensation for field stability.
• Measured COD, turbidity and temperature data are available over RS485 Modbus-RTU for PLC, SCADA and data-acquisition integration.
