8 standard COD digesters, 8 standard COD digesters for 250ml flasks
KHC0D-8K national standard COD digestion device adopts special heating plate. When heating, the surface heats evenly, and the temperature rises and cools down quickly.
Another innovation of KHC0D-8K national standard COD digestion device adopts constant temperature control to control the heating temperature of the surface of the electric furnace. The digestion time can be set. After the digestion is completed, the instrument automatically stops heating, and the instrument fan continues to work for half an hour, and the auxiliary sample is cooled, which can be left unattended.
KHC0D-8K national standard COD digestion device adopts microcomputer technology for timing control heating electric furnace, which can simultaneously heat eight 250ML cone digestion reflow devices.
