iCOD-306 Online COD Sensor

Many organic substances dissolved in water absorb ultraviolet light. Therefore, by measuring the absorption of these organic substances by ultraviolet light at a wavelength of 254 nm, the total amount of dissolved organic pollutants in water can be accurately measured. The iCOD-306 online COD sensor uses two light sources, one 254nm ultraviolet light and one 365nm ultraviolet reference light, which can automatically compensate the optical path attenuation and eliminate the interference of the granular suspended matter enamel to a certain extent, thus achieving more stable and reliable. No reagents, no pollution, more economical and environmental protection Small size, easy installation, and continuous water quality monitoring Measure COD, turbidity and temperature parameters Automatic compensation for turbidity interference With a cleaning brush to prevent bio-adhesion Small drift, fast response, more accurate measurement Excellent stability even for long-term monitoring Maintenance-free, long service life and low cost of use Digital sensor, RS-485 interface, Modbus/RTU protocol Low power design, anti-interference design
