MC Series Controllers

Mass Flow Controllers with Laminar Differential Pressure (DP) Technology

Mass flow controller products from Alicat

Our most versatile gas flow controllers for most industrial processes and research applications.

  • Laminar DP (differential pressure) mass flow measurement technology
  • 98-130 pre-loaded gas calibrations — switch without losing accuracy
  • Measures mass flow, volumetric flow, temperature, and pressure
  • Ultra–fast control response time as low as 30 ms
  • As high as 0.01 – 100% measurement and control range (10,000:1 turndown)
  • Limited Lifetime Warranty

Full Scale Flow Ranges

0.5 SCCM – 10,000 SLPM

OPERATING PRESSURE RANGE

11.5 – 160 PSIA
