Vacuum Mass Flow Controllers
Mass Flow Controllers for Sub‑Atmospheric Flow Systems
Vacuum mass flow controllers are preconfigured to easily fit, and work, in vacuum processes—like CVD, ALD, PVD and coating. These instruments measure and control gas flow from 0.5 SCCM full scale to 20 SLPM full scale.
- Ultra-fast response time as low as 30 ms
- Up to 130 pre-loaded gas calibrations — fewer spares: switch without losing accuracy
- Use fewer units: As high as 0.01 – 100% measurement and control range (10,000:1 turndown)
- Accuracy as good as ± 0.4% of reading and ± 0.2% of full scale
- Laminar differential pressure (DP) mass flow measurement technology
- Measures mass flow, volumetric flow, temperature, and pressure
- Limited Lifetime Warranty
0.5 SCCM – 20 SLPM
11.5 – 160 PSIA
MCV Series Controller
