Technical Feature

●The host adopts a 7-inch color touch screen, with a user-friendly human-machine exchange interface.

● Computer reverse control and host touch screen achieve synchronous bidirectional control.

●A multi-core, 32-bit embedded hardware system ensures the reliable operation of the instrument.

● Digital display of carrier gas/hydrogen/air path flow (pressure).

●Equipped with air shortage alarm protection function; Heating control protection function (when opening the column box door during use, the column box fan motor and heating system automatically turn off).

●The split flow rate/split ratio can be automatically controlled to save carrier gas.

●Configure the installation and positioning interface of the automatic sampler, which can match various specifications of automatic samplers.

●The data collection is equipped with a standard dual channel data collection card, with a sampling time of 50ms.

●Using a logarithmic amplifier board, the detection signal has no cut-off value, and the synchronous external trigger function can be used to start the host and workstation simultaneously by external signals (such as automatic samplers, thermal analyzers, etc.).

●Equipped with comprehensive system self inspection function and automatic fault identification function.

●Equipped with an extended functional interface for 8 external events, it can be equipped with various control valves and operate according to its own set timing.

●The external connection method is network port connection (RJ45), providing convenience for remote control of data.
