Introduction: Chemical oxygen demand (Chemical Oxygen Demand, COD for short) refers to the amount of oxygen required for oxidizable substances in wastewater to be oxidized by chemical oxidants, expressed in mg/L of oxygen. COD is currently a common method used to determine the content of organic matter in wastewater; it is also an important indicator for evaluating the degree of water pollution, and is a routine measurement item in water quality monitoring and analysis (the larger the COD, the more serious the water body is polluted by organic matter. ). The SH-8801 COD rapid method automatic analyzer is a new type of intelligent automation product developed in combination with the current needs of laboratory water quality intelligent analysis; the successful development of this product indicates that the domestic COD rapid method has entered the era of automation in advance, and the advent of this product fills in In the laboratory, there is no blank of the domestically-made COD fast method automatic analyzer. The instrument automates the cumbersome and complex COD analysis, frees the hands of the inspectors, and is a powerful laboratory helper. The instrument adopts a precision three-axis mechanical arm design, with automatic functions such as sampling, opening and closing the bottle cap, cleaning, mixing, digestion, and detection in the whole process; it realizes the whole process of COD rapid method analysis unattended, water sample batch processing, and result display printing , Automatic storage and access to the Internet of Things cloud database and other functions, which can manage, edit and comprehensively analyze all batch inspection data; the machine is equipped with an 8-inch IPS high-definition touch screen, equipped with the company’s new AOS operating system, which reflects powerful The human-computer interaction interface, the application of national standard methods and the combination of personalized menu operations, ensure that the entire analysis process is simple, efficient and accurate. This product is based on the national standards: HJ/T 399-2007 method standard and HJ 924-2017 instrument standard; it also meets the verification regulations of GB/T 32208-2015 chemical requirement analyzer; it also complies with GB/T 12519-2010 analytical instrument Production requirements of general technical conditions. This product can be widely used in universities and research institutes, environmental monitoring (third-party testing), sewage plants, water conservancy, environmental protection engineering, petrochemical industry and other laboratories COD analysis of water quality.
