Description
1. The host machine adopts a 7-inch color touch screen with a friendly man-machine interface.
2. Computer back control and host touch screen to achieve synchronous bidirectional control.
3. The multi-core, 32-bit embedded hardware system ensures the reliable operation of the instrument.
4. Carrier/hydrogen/air flow (pressure) digital display.
5. Gas shortage alarm protection function; Heating control protection function (when opening the door of the column box, the motor of the column box fan and the heating system will shut down automatically).
6. Split flow/split ratio can be automatically controlled to save carrier gas.
7. Configure the automatic sampler installation and positioning interface to match the automatic sampler of various specifications.
8. Data acquisition is a standard dual-channel data acquisition card with a sampling time of 50ms.
9. Using a logarithmic amplification plate, the detection signal with no cut-off value, synchronous external trigger function, can be started by external signals (automatic sampler, thermal analyzer, etc.) at the same time as the host and workstation.
10. It has a perfect system self-check function and a fault automatic identification function.
11. With an eight external event extension function interface, can be selected with a variety of control valves, and according to their own set time sequence work.
12. The external link mode is a network port connection (RJ45), which provides convenience for remote control of data.
