Instrument features:

• Full microcomputer control system, computer control. One computer can control N (N≦253) chromatographs. It has a six-way temperature control system and a four-way time program system.
• The chromatograph adopts a 10/100M Ethernet communication interface, which can realize remote control of the instrument and remote data transmission, processing and supervision. Can be connected to unit supervisors and superior supervisors to facilitate supervision by supervisors.
• Digital signal output (built-in chromatography workstation), signal network cable output directly.
• The large-capacity column oven is equipped with an automatic rear door and can perform 8-step program temperature rise; it has a near room temperature control function (8℃ above room temperature).
• It has a fault self-diagnosis function, which can display the fault location and nature at any time; it has an over-temperature protection function, and any path temperature that exceeds the set temperature will automatically stop.
