Product Description
ETT-GC9790II Series gas chromatograph is a new generation of products developed in the ETT-GC9790 gas chromatograph on the basis of the structure and performance optimization, the use of microcomputer control system and big screen in the display, control and analysis done on the PC all the work, but also optional built-in AD converter circuit, direct digital output of chromatographic signals. Stable performance, easy operation, reliability, and are widely used in petroleum, chemical, pharmaceutical, food, environmental protection, disease control, research institutions, as well as quality inspection departments.
Product Features:
First bus control platform, can be modular extension of the chromatographic system
Through the bus control platform to ensure the accuracy of the various types of data transmission, to further improve the reliability and stability of the instrument.
The high sensitivity of the PC control system, perfect for online monitoring
Optional anti-control system, to achieve more functionality.
Classic LCD screen design, parameter setting is simple and intuitive
Large-screen LCD, a richer amount of information, the humanized key design and user interface to ensure an intuitive, easy to operate.
Reliable anti-jamming system, over-temperature protection
Inherited six ETT-GC9790 gas chromatograph temperature control system and a zero pulse to trigger the control system to optimize the reliability is stronger.
Improve the self-diagnostic function, the failure to retrieve is no longer
Real-time feedback to equipment failure information, and user-friendly retrieval failure, to ensure that the instrument easy to maintain.
