COD online water quality monitor
Model：ERUN-SZ2-B-J5
Parameter: COD
Based on the principle of ultraviolet absorption method, by measuring the degree of absorption of these organic substances on the 254nm wavelength ultraviolet light, you can accurately measure the dissolved COD organic pollutants in the water content, the sensor does not require reagents, pollution-free, more economical and environmentally friendly, internal integration of all the way to the turbidity detection of the light source, the turbidity of the water body to be measured by the interference of automatic compensation. With automatic cleaning brush device, even if long-term monitoring still has excellent stability, a wide range of surface water, industrial discharges of sewage, sewage plant water quality COD for continuous real-time monitoring.
