Domestic standard COD digester heating temperature control method-the latest technology of standard COD digester
At present, all the standard COD digesters in China only have heating and countdown functions. The heating plate is a silicon carbide ordinary electric furnace plate, the size is 20x30cm, and then the electric furnace wire is installed. It is the most common heating device. Customers choose as long as the power of the fan, the material of the electric furnace plate, the power of the heating wire, the number of digested samples, and the choice of heating bottles (6 250ml conical bottles, 8 300ml and 10 200ml cylindrical bottles) , Its heating power is fixed (normal 1200-1500W), no difference in other aspects.
KHCOD-8Z standard COD digestion device, it is an upgraded product of standard COD digestion device, the heating plate is changed to a special customized insulation material, pressed and sintered, using a microcrystalline glass plate to heat the table, size: 42 × 22cm, microcrystalline heating The plate is a single piece, the installation and replacement of the electric stove plate is very simple, the overall structure of the heating plate, the space heating, the maintenance and replacement is very convenient, at the same time, the dual fan cooling, the cooling effect is very good, can digest 8 250ml conical flasks or 12 300ml Cylindrical sample.
Through comparison, each has its own strengths, combining the structure and practicality of various instruments, we have upgraded on the basis of KHCOD-8Z standard COD digestion device.
KHCOD-8K type national standard method COD heating reflux device, changed to liquid display Chinese display, display standby, heating, cooling, display the actual temperature of the heating platen table, display heating time countdown, at a glance, and added stepless pressure heating , Self-adjusting the most recognized heating power, without affecting the temperature of spring, summer, autumn and winter, can ensure that the customer has the best boiling effect. Double fan cooling, the cooling effect is very good. KHCOD-8K standard COD digestion device is now in mass production and sales, and applied for practical patent technology.
