Product Description

Technical features:

  • The host uses a 7-inch color touch screen, electronic display gas flow and pressure values.
  • computer anti-control (need to choose PC-side anti-control software) and the host touch screen to achieve synchronous two-way control.
  • Multi-core, 32-bit embedded hardware system to ensure reliable operation of the instrument.
  • One key to start function.
  • Extensible synchronous external triggering function can be initiated by external signals (autosampler, thermal analyzer, etc.) at the same time to start the host and workstation.
  • Has a perfect system self-test function and automatic fault recognition.
  • Extended interface with 8 external events, which can be equipped with various function control valves and operate according to their own timing.
  • 20 sets of sample test mode memory function.
  • RS232 communication port
