It measures the absorption of 254 nm ultraviolet light by dissolved organic matter to determine the concentration of dissolved organic pollutants in water. The sensor requires no reagents and generates no chemical waste, making it a cost-effective and environmentally friendly solution. An integrated turbidity-detection light source provides automatic turbidity compensation, while the automatic cleaning brush helps maintain stable long-term performance during continuous monitoring.\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cspan\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003ch2\u003eMain Features\u003c\/h2\u003e\n\u003cul type=\"disc\" style=\"margin-top: 0cm;\"\u003e\n\u003cli style=\"mso-list: l0 level1 lfo1;
