COD Water Quality Sensor (UV Absorption Method)
Many dissolved organic compounds in water absorb ultraviolet light. By measuring absorption at 254 nm, the total amount of organic pollutants can be quantified. The AMT-COD300 intelligent COD sensor uses a dual-light source design: 254 nm UV for measurement and 365 nm UV as reference. This configuration automatically compensates for optical attenuation and eliminates interference from suspended solids, ensuring more stable and reliable results.
