Gas Chromatograph (equipped with full EPC/EFC)

GC2003 Gas Chromatograph (equipped with full EPC/EFC)

Main Features of GC2003 network gas chromatograph:

1. Full microcomputer control system, computer reverse control, one computer can control N (N≤253) chromatographs, and has a seven-way temperature control system.

2. The chromatograph uses an RJ45 network cable output interface, which is simple and convenient to control and collect. It can realize remote control of the instrument and remote data transmission, processing and supervision. It can be connected to the unit supervisor and superior supervisor to facilitate supervision by the supervisor.

3. Built-in workstation, digital signal output (analog signal output can also be selected), the signal is directly transmitted to the computer through the network cable, and the computer software can directly control the instrument, making it easy to operate.

4. Optional color 5.7-inch or 8-inch touch screen, intuitive human-machine dialogue.

5. The large-capacity column oven has an automatic rear door, which can be set to 16 levels of programmed temperature rise, and can also be expanded to more levels of programmed temperature rise (can be edited to countless levels);

6. The mainboard is equipped with 8 external event time programs, which can realize online cycle monitoring.

7. The reverse control interface of the chromatography workstation can set the signal collection time program of any two or three detectors, and the signals of three detectors can be collected in the same data processing channel;

8. It has the function of self-diagnosis of solid faults, which can display the location and nature of the fault at any time. It has the function of over-temperature protection. If the temperature of any path exceeds the set temperature, it will automatically stop heating.
