SEC-Z700X Series
Pressure Insensitive Mass Flow Controller
The SEC‑Z700X Series is equipped with reliable thermal sensors and a pressure‑insensitive function for stable flow rate control. Its on‑board pressure measurement reduces the cost, size, and complexity of gas delivery systems.
Why Choose SEC-Z700X Series
- Multi‑Gas / Multi‑Range functionality: user‑adjustable gas type and full‑scale flow
- Variable PID control: high‑speed response within 1 s across full flow range
- Pressure‑insensitive design: stable flow unaffected by upstream/downstream fluctuations
- Compact gas line: no regulator, transducer, or filter needed
- Integrated inlet pressure sensor & on‑board multi‑display: real‑time flow, temperature & pressure readings
- Ultra‑clean stainless steel SUS‑316L diaphragm with polished surface treatment
