Domestic standard COD digester heating temperature control method

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, easy maintenance, at the same time, the double fan cooling, the cooling effect is very good, you can digest 8 250ml Erlenmeyer flasks or 12 300ml columns at the same time Sample of shaped bottle.

The COD simmer heater is designed for constant temperature heating. It uses an aluminum block to heat 12 cylindrical bottles. A special long cooling tube is used for natural cooling.

Through comparison, each has its own strengths, integrating the structure and practicality of various instruments, we have upgraded on the basis of the 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 board table, display the heating time countdown, at a glance, at the same time added to the circuit stepless voltage regulation heating function, self-adjusting the most recognized heating power, without affecting the temperature of spring, summer, autumn and winter, can be guaranteed Customers have the best boiling effect. Double fan cooling, the cooling effect is very good.
