QT720 Series Multi-Gas Mixing System

The QT720 Series combines differential-pressure-based mass flow controllers with gas mixing modules for real-time pressure or flow control. It supports MQTT communication, automated operation, and data logging. Standalone, benchtop, and rack-mounted configurations are available, with data export to CSV files, databases, or cloud platforms.

Mixing Accuracy: ±0.6% (100sccm~20SLPM)
Calibration Accuracy (50–5000 SLPM): ±0.8% R.D. or ±0.2% F.S.
Repeatability: ±(0.1% R.D.+0.02% F.S.) (100sccm~20SLPM)
Compatible Gases: 49 pure gases + 5 custom gas mixtures
