Model IMFS

Model IMFS

Instrument Applications:

  • Mass Extraction at vacuum under 0.2 psia (hard vacuum)
  • Leak Detection of 0.1 to 0.2 micron defects
  • Air measurements from 5 x 7-7 sccs
  • Intelligent Molecular Flow Sensor - operates mostly in transitional and molecular flow regimes
  • Outgassing / Premeability application
  • Calibration of leak devices
Leak Test Simulator button

Features:

  • Intelligent Molecular Flow Sensor - Operates mostly in transitional and molecular flow regimes
  • Measures mass flow, using ATC's patented ALF design
  • Measures hard vacuum to 15 psia
  • Rugged, stainless steel construction
  • No moving parts

The IGLS is a part of ATC's complete leak test instruments, portable unit, or part of a larger automated test system. The micro-flow sensor is not available by itself.
