TC-100C standard COD digester

Product introduction: The TC-100C biao zhun COD digestion device follows the basic principles of international biao zhun (ISO) and biao zhun (GB), ensuring a digestion operation of reflux heating and micro boiling for 2 hours. The preparation and addition of reagent solutions are consistent with the GB method, ensuring reliable and accurate analysis results. The TC-100C biao zhunCOD digester adopts microcomputer technology for timed control of the heating electric furnace, which can simultaneously heat 5 (customized), 6 (standard), and 10 (customized) digestion cone reflux devices. To achieve the goals of energy conservation, reducing power load, water conservation, and improving efficiency. At the same time, glass burr reflux pipes are used instead of spherical reflux pipes, and air cooling technology is used instead of tap water cooling, which can not only save water and standardize the instrument, but also improve the safety of instrument use. The chemical solution preparation, operation, and COD value calculation of the biao zhunCOD digester fully comply with GB11914-89. Water samples with COD values below 50mg/L can improve accuracy by diluting titrants and oxidants, while water samples with COD values above 1000mg/L can be measured by diluting the water sample proportionally. The analysis method of biao zhunGB11914-89 standardizes the determination steps of chemical oxygen demand (COD) for water quality, and strictly specifies the conditions and indicators such as heating digestion time, solution acidity, and oxidant dosage for the method. It is obvious that the determination of COD (cr) in water quality is strict
