Technical features:

The host adopts a 7-inch color touch screen, with a 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 reliable operation of the instrument.

The air circuit has flow and pressure display.

Scalable synchronous external triggering function, which can simultaneously start the host and workstation from external signals (such as automatic sampler, thermal analyzer, etc.).
