Fits corrosive-gas mass flow control where you need an Alicat Scientific MCS / MCRS Series. Anti-corrosive stainless steel controllers spanning 0.5 SCCM to 12,000 SLPM full scale, standard accuracy ±(0.8% reading + 0.2% FS), high-accuracy ±(0.4% reading + 0.2% FS) for ≥5 SCCM and ≤500 SLPM, repeatability ±0.2% FS, and control turndown 1–100% FS (100:1).
Key advantages
- Wetted — Anti-corrosive stainless steel
- Range — 0.5 SCCM to 12,000 SLPM FS
- Accuracy — ±(0.8% rdg + 0.2% FS) std
- Turndown — 100:1 (1–100% FS)
- Repeatability — ±0.2% FS
Typical applications
- Corrosive gas control.
- Specialty gas MFCs.
- SS wetted process loops.
Selection guide
- Full scale / gas
- MCS vs MCRS
- Elastomers / fittings
Common mistakes
- Wrong elastomer for gas.
- Ignoring 100:1 turndown.
- FS mismatch.
When to RFQ / what to tell us
