The standard method for the determination of COD is using Reflux titration method, which long digestion time (two hours), energy consumption, high reagent costs, inefficient, and often troubled actual operator. Even China Science and Technology in the early 1980s, invented the method of rapid determination of chemical oxygen demand in wastewater (COD) --- catalyze the rapid method. Chemical oxygen demand (COD) is often used as a measure of how much organic matter content in the water. The larger cod COD direct detector, indicating more serious water pollution by organic matter. Even China Science and Technology is one of the earliest manufacturers to develop water quality monitoring equipment, and even China independently designed and developed a number of products. Include: COD analyzer, ammonia analyzer, TP analyzer, total nitrogen analyzer, BOD5 meter, heavy metal detector, multi-parameter water quality analyzer, water quality monitoring instrument, please contact us! 5B-3C (V8) model to select the measurement mode of the instrument according to the measured concentration of COD in water samples were divided into high range and low range measurements. High Range Range in 50-1500mg / L cod detector, commonly used in the determination of high concentrations of sewage Guangzhou cod detector, according to the high range and press the OK button to select this mode, watery than the color should be placed in the high range cuvette ; low range measurement range 5-150mg / L, commonly used in the determination of low concentrations of surface water, according to the lower range and press the OK button to select low-range mode, watery than the color should be placed in the low range cuvette. Guangzhou cod detector, even Chinese brands (certified), cod detector provided by the Environmental Protection Technology Co., Ltd. in Guangzhou, China even. Even China Guangzhou Environmental Protection Technology Co., Ltd. (www.gdlhkj.com) (www.gdlhkj.cn) is Guangzhou, analytical instruments leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum meet customer needs.
