IS-Max™ Intrinsically Safe Mass Flow Controllers

Mass Flow Controllers for Explosive Atmospheres

IS-Max Series: Intrinsically Safe Mass Flow Controllers by Alicat
IS-Max intrinsically safe flow controllers have IECEx and ATEX Zone 0 certificates. These instruments can measure and control flow of gases from 0.5 SCCM full scale to 250 SLPM full scale in explosive gas atmosphere hazardous locations.

  • Flow accuracy as great as ± 0.5% of reading or ± 0.1% of full scale, whichever is greater
  • Laminar differential pressure (DP) measurement technology
  • Up to 128 pre-loaded gas calibrations — switch without losing accuracy
  • Measures mass flow, volumetric flow, temperature, and pressure
  • As high as 0.01 – 100% measurement and control range (10,000:1 turndown)
  • IP66 enclosure
  • See certificates below
Full Scale Flow Ranges
