KHC0D-6K intelligent standard COD digestion device uses microcomputer technology for timing control heating furnace, which can simultaneously heat six 250ML cone digestion reflow devices.
KHC0D-6K intelligent standard COD digestion device is another innovation, using constant temperature control, can control the surface heating temperature of the electric furnace plate.
KHC0D-6K intelligent standard COD digestion device can set the digestion time. After the digestion is completed, the instrument automatically stops heating. The instrument fan continues to work for half an hour, and the auxiliary sample is cooled, which can be left unattended.
The KHC0D-6K intelligent standard COD digestion device uses a glass burr return tube instead of a spherical return tube, and replaces the tap water return cooling method with air cooling technology, and assists cooling with static water at the end of the condensing tube, both air-cooled and water-cooled. Improve the safety of the instrument.
