GC-7820
Network Power Gas chromatograph
SPECIFICATIONS
GC-7820 power gas chromatograph by injector, detector, chromatographic column box, nickel reformer, gas flow control system, circuit control detection system and network version of dedicated workstations etc..
Design the appearance of the atmosphere, the reasonable structure of the GC-7820 network power gas
chromatograph, simultaneously loaded my company independent research and development of color display technology, electronic control technology of gas flow. The automation level and the overall performance is greatly improved. In addition to the instrument unique network remote transmission and control function, make the instrument in unattended, decentralized monitoring, centralized control can be a reality.
1.The first Internet communication technology, modular expansion of the chromatographic system.
Through the local area network, long-distance data transmission is realized, which ensures the accuracy of various types of data transmission, and further improves the reliability and stability of the instrument.
2.Highly sensitive PC control system for perfect online monitoring.
Optional anti-control system for more functions.
3.Classic LCD large screen design, parameter settings are simpler and more intuitive.
The large-screen liquid crystal display is rich in information, and the user-friendly button design and operation interface ensure intuitive and easy operation.
4.Reliable anti-jamming system, over-temperature protection.
The gas chromatograph's six-way temperature control system and zero-crossing pulse trigger control system are optimized for greater reliability.
5.Complete self-diagnosis function, fault retrieval is no longer complicated
Real-time feedback of instrument fault information makes it easy for users to retrieve faults and ensure that the instrument is easy to maintain.
