YHC0D-8Z Microcrystalline Plate Standard COD Digestion Device Introduction: The YHC0D-8Z microcrystalline plate standard COD digestion device uses a specially designed electric furnace slot for heating, with a high-temperature microcrystalline plate heating surface. When heating, the surface heats evenly, and the heating and cooling rates are fast. At the same time, the sample solution accidentally drops onto it, which naturally evaporates, reducing damage to the instrument caused by improper operation. The YHC0D-8Z microcrystalline plate standard COD digestion device can set the digestion time and display the countdown of the digestion time. After the digestion is completed, the instrument automatically stops heating, and the instrument fan continues to work to assist in sample cooling. It can be left unattended. The YHC0D-8Z standard COD digestion device uses a glass burr reflux pipe instead of a spherical reflux pipe, and uses air and water cooling technology to replace circulating water cooling, making operation more convenient. The cooling part is mainly completed by water cooling of the burr condenser tube and fan air cooling. The upper part of the condenser tube is spherical with 3 bubbles, which has better cooling effect. The catalyst is added here to prevent the instantaneous evaporation of light components in the sample, and the evaporation cap can be covered. The lower part is in the shape of "burrs", with three opposite "cold bubbles" protruding from the condensing tube wall on a plane, which increases the cooling area and can block the passage of volatile substances and vapors compared to a simple spherical condensing tube. In addition, the dual effect of cooling water and internal fan in the spherical reflux tube is added, and the YHC0D-8Z standard COD digestion device ensures the reflux cooling of the sample. The upper inserted burrs reflux tube is safer and more stable to use. Technical parameters: Measurement range: 5-700mg/L; Determination after dilution of 700mg/L-10000 mg/L water sample Digestion time: 1 minute to 2 hours and 30 minutes (user can choose heating time independently) Measurement error: The relative standard deviation of potassium hydrogen phthalate standard solution (500mg/L) shall not exceed 5.0%; The relative standard deviation of industrial organic wastewater (500mg/L) shall not exceed 8.0% Environmental temperature: ≤ 40 ℃ Number of digestion samples: 8 250ml conical flasks, divided into two rows and simultaneously heated for digestion Heating power: ≤ 1600W (AC 220V, 50HZ) Instrument size: 490 * 290 * 605mm (H)
