Chemical Oxygen Demand and Water Quality Online Automatic Monitoring Instrument

Chemical Oxygen Demand Online Automatic Monitoring Instrument is a fully automatic online monitoring instrument launched by Tianjin Tongyang Technology Development Co., Ltd. based on years of research on water quality analysis products. Heat a mixture of water sample, potassium dichromate solution, silver sulfate solution (silver sulfate added as a catalyst can more effectively oxidize linear fatty compounds), and concentrated sulfuric acid until165℃After the oxidation of organic compounds in a solution by dichromate ions, the color will change. Within the measurement range of the instrument, the degree of color change is related to the sampleCODThe concentration is directly proportional, therefore, by measuring the degree of color change through the photoelectric colorimetric method, the sample can be calculatedCODThe concentration.
