1. Characteristics - High degree of automation:
based onWindowsChinese operation interface, direct human-machine dialogue. The collection, processing, storage, and printing of data are controlled by computers.The instrument automatically adjusts gas flow rate, samples, cleans, changes samples, generates standard curves, and goes into sleep mode after the analysis process is completed. It can also be set to wake up at regular intervals, fully realizing unmanned analysis.
