Product 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 a 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 functions.
