Introduction: The SH series of national standard COD intelligent reflux digestion instrument is designed in full accordance with the basic principles of the standard HJ 828-2017 (instead of GB 11914-89) issued by the Ministry of Environmental Protection, which can effectively ensure the digestion of the reflux micro-boiling constant temperature control heating for 2 hours. The process, the preparation of the reagent solution and the addition amount are consistent with the requirements of the HJ 828-2017 standard, which can ensure accurate analysis results. The instrument adopts microcomputer technology to control the heating mode in time sequence, and can choose to heat the all-glass reflux device of 6/10/12 250ml conical flasks with ground mouth at the same time; to achieve the purpose of energy saving, reducing power load and improving efficiency. The instrument uses a glass burr return tube instead of a spherical return tube, and uses air-cooling and water-cooling technology to replace the tap water cooling method, which can save water and reduce the placement space and standardize the instrument. At the same time, it also improves the reliability of the instrument. The use of fashionable microcrystalline optical panel design concept not only improves the accuracy of sample digestion, but also improves the aesthetics of the product. Features: 1. Dual fan convection cooling can be controlled independently, and the cooling effect is remarkable 2. Comes with 7-inch touch color screen, one-key selection of Chinese menu 3. Time and power are adjustable, and users can modify, set and save by themselves 4. Using microcrystalline heating panel, infrared heating method, the heating speed is fast and uniform, and the service life is longer 5. After the digestion is completed, the instrument will automatically beep to remind and stop heating 6. Water-saving and electricity-saving, small heat radiation and small space occupation 7. Simple operation, which can effectively reduce costs and improve work efficiency Technical parameter: Measuring range: 4～700mg/L, 700～10000mg/L (water sample must be diluted) Measuring time: ≤150 minutes (the time can be set according to user needs) Measurement error: standard solution of potassium hydrogen phthalate (500mg/L), relative standard deviation not greater than 5.0%, industrial wastewater (500mg/L), relative standard deviation not greater than 8.0% Ambient temperature: -5～40℃ Display mode: 7-inch high-definition touch screen interface Digestion samples: 10/12/batch Digestion time: The time can be set according to user needs, 1-999 minutes Fan setting: automatic/manual Heating power: 1200W (AC 220V±22V, 50HZ)
