The COD intelligent digestion instrument uses microcomputer technology to adjust the heating electric furnace, which can heat up six digestion cone reflux devices together. To achieve the goals of energy conservation, reducing power load, and improving work efficiency. The instrument equipment uses glass burr reflux pipes instead of spherical reflux pipes, and uses air cooling technology instead of tap water cooling method, which can save water and standardize the instrument equipment, and also improve the safety factor of instrument equipment use. The instrument equipment is also equipped with a pneumatic sampling device and an automatic zeroing burette, which simplifies the later titration operation procedures and improves the safety and reliability of the method.
Functional Features
Dual fan convection cooling, can be controlled separately, with obvious cooling effect;
Large screen display with LCD Chinese subtitles, adjustable for time and power, allowing users to adjust, set, and store independently;
Using stainless steel heating tubes for heating, the heating speed is fast and uniform, and the service life is long;
After successful digestion, the instrument and equipment will automatically sound an alarm and terminate operation;
Water saving, low electric and thermal radiation, and small space occupation.
