Online COD Analyzer (Electrode Method)
Product Introduction
The COD sensor uses advanced deep-ultraviolet UV LED cold light source, with long service life and small drift. It adopts international general technology and a proven high-precision ultraviolet absorption method. No sample pretreatment, reagent addition, or sampling equipment is required. The sensor has a mechanical self-cleaning function and uses a 550nm compensation light source, which can effectively eliminate the influence of turbidity and color on the measurement.
