Measurement Techniques

Pressure Insensitive
A new high-performance function provides a simplified gas supply systems.
Typical multi chamber gas lines have a line regulator, pressure sensor and filter to avoid mass flow controller crosstalk phenomenon caused by pressure fluctuations.SEC-Z700X Series  exhibit high stability and control the gas flow without effect of upstream and downstream pressure fluctuations. They not only give a flow rate output but also the temperature and pressure readings.
