| Model | RMZN551-B/C |
|---|---|
| Output | RS-485,MODBUS |
| Power supply | 0.25W(not rotating brush),0.8W(rotating brush) |
| Application | Sewage treatment plant Industrial wastewater monitoring Surface water and lake monitoring Drinking water safety guarantee Aquaculture industry Environmental protection monitoring system. |
| Description | The RMZN551-B/C self-cleaning COD sensor is based on the principle of ultraviolet absorption method, and can accurately measure the content of dissolved organic pollutants in water by measuring the absorption degree of these organic substances to 254nm wavelength ultraviolet light. The sensor requires no reagents, no pollution, and is more economical and environmentally friendly. One turbidity detection light source is integrated in the interior, and the turbidity interference of the measured waterbody is automatically compensated. With automatic cleaning brush device, even long-term monitoring still has excellent stability. |
