AHF901 EPC Gas Chromatograph
Main features
► It can realize full EPC electronic flow control and full computer control of the gas chromatograph;
► High-precision gas flow ensures the accuracy and stability of GC analysis and daily analysis efficiency, and the EPC control accuracy is 0.01psi;
► Achieves self-protection against gas circuit failures, automatic ignition, and one-button start;
► Adopts advanced 10/100M adaptive Ethernet communication interface and built-in IP protocol stack to easily form a local area network to achieve long-distance transmission, remote control, and remote diagnosis;
► Equipped with IBrainChrom® workstation, which can support multiple chromatographs (253 units) working at the same time to achieve data processing and reverse control, reaching an industry-leading level;
The built-in Modbus/TCP server of IBrainChrom ® workstation can easily connect the analysis results to DCS (distributed control system).
