GC-9860 PlusThe networked gas chromatograph is used in our companyGC-9860On the basis of the upgraded model, the appearance is grand and the structure is reasonable. At the same time, our company's independently developed color screen display technology and gas electronic flow control technology are loaded. This has significantly improved its automation level and overall performance. Especially with the successful development and application of gas electronic flow control technology, the gap between domestic and imported models has been shortened. In addition, the unique network remote transmission and control functions of this instrument make unmanned, decentralized monitoring, and centralized control a reality.
