1、 Main functions:

The TC-200A COD rapid analyzer isOur company is200typeCODA upgraded and modified version based on the measuring instrumentCODQuick measuring instrument. This itemCODThe measuring instrument is equipped withPIDThe automatic adjustment technology and other functions enhance the accuracy and stability of the instrument; Additionally, this itemCODThe built-in micro thermal printer and other features of the measuring instrument greatly facilitate the use of laboratory personnel. Widely used in various industries such as laboratory testing, sewage treatment, colleges and universities, environmental monitoring, sewage treatment, as well as colleges and research institutions.

The TC-200A COD rapid analyzer can use open tube reflux heating digestion or sealed digestion methods. The instrument uses specialized catalysts and oxidants. After adding specialized oxidants and catalysts to the water sample, it is heated and digestedCr6+Partially restored toCr3+After restorationCr3+The content is determined by colorimetric analysis and regression calculation, and converted into the water sampleCOD(cr)The actual concentration. The design performance of TC-200A COD rapid analyzer meets the national environmental protection industry standards《HJ/T 399-2007water quality Determination of Chemical Oxygen Demand The rapid digestion spectrophotometric method is required. It can be widely applied to the detection of wastewater from various industries (industrial wastewater, urban sewage, domestic sewage, and surface water in rivers and lakes).
