DF-550C is now released as an all-metal model of the high-performance digital mass flow controller DF-250C Series. The metal sealed structure enables controlling the measurement of corrosive gases such as semiconductor process gases.
Features
- Response improved to 1 sec or faster in all flow rate ranges thanks to a new solenoid
- The stainless steel seal supports high-reactive gases.
- Lineup ranging from 10 SCCM to 10 SLM
- Two communication ports enabling daisy-chaining
- RS-485 communication function installed as standard
- RoHS CE standard compliant
