The ultraviolet absorption method is a commonly used method for the determination of chemical oxygen demand (COD). The COD sensor principle is to irradiate the sample with ultraviolet light to make the organic matter absorb under the action of ultraviolet light, measure the intensity of the absorbed light, and calculate the COD value in the sample. Its characteristics are as follows:
1. High sensitivity: The ultraviolet absorption method COD sensor has high sensitivity to organic matter, and can measure COD values at low concentrations.
2. Quick and easy: The process of measuring COD by ultraviolet absorption method is simple and fast, does not need to use complicated instruments and equipment, and is easy to operate.
3. High reliability: The results of COD determination by ultraviolet absorption method are stable and reliable, with high accuracy and repeatability.
4. Wide applicability: The UV absorption method TOC COD sensor can determine the COD value in various types of water samples and wastewater samples, and has wide applicability.
5. The types of substances that can be measured are limited: the online COD sensor can only measure the COD value of organic substances, and the measurement effect on inorganic substances is poor.
