The series of device of intelligent COD clear up of research and development of company of instrument of analysis of Nanjing division annulus, have temperature indication, precision tall, scope of application wide, function is powerful wait for a characteristic, accord with a country each technology index, put program of many clear up beforehand, intelligence changes a course taller. Device of clear up of KHCOD-8Z standard COD followed international standard (ISO) and national level (the basic principle of GB) , made sure circumfluence heats clear up of 2 hours operates small boil, make up and join a quantity of reagent solution to agree with GB law, ensure reliable and accurate analysis result. COD clear up implement use canal of vitreous burr circumfluence to replace globose circumfluence tube, replace kind of tap water refrigeration with wind cold technology, already can section water can make again instrument standardization, still enhanced the security that the instrument uses at the same time. Of characteristic of function of device of clear up of KHCOD-8Z standard COD define: Device of clear up of KHC0D-8Z standard COD, use personal computer technology, reasonable design, but cone-shaped to 8 250ML bottle undertakes heating at the same time circumfluence clear up. Method of level of state of GB11914-89 of complete comply with, choose silk of high grade electric stove, heat correctly power, small boil 2 hours. Device of clear up of KHCOD-8Z standard COD, use tailor-made and special hot plate board heat, the surface when heating is calorific and even, warm up, drop in temperature rate is rapid. At the same time sample solution drips not carefully go up, volatilize naturally, can reduce an operation undeserved the attaint to the instrument. Device of KHCOD-8Z COD clear up, can time of set clear up, time of indication clear up times, after clear up ends, the instrument stops automatically to heat, instrument double fan continues to work, auxiliary sample is cooling, but unmanned guard. Device of KHCOD-8Z COD clear up, use canal of vitreous burr circumfluence to replace globose circumfluence tube, replace kind of circular water refrigeration with cold technology of wind Leng Heshui, the operation is more convenient. Cooling part basically is in charge of wind of water-cooling zephyr fan by burr condensation cold finish, condensation is partly on the canal globose 3 bubble, cooling effect is much better, one key is operated, the clear up that finish, cooling process.
