Scalable Pressure or Flow Leak Testing 

The Sentinel MH is an advanced, multi-function differential pressure leak test and mass flow instrument designed to achieve high-resolution measurements with fast and repeatable results. 
  • High-speed leak testing for improved cycle times
  • Modular mounting capabilities offer scalable installation options and reduced system volume
  • PLC communications via serial or Ethernet/IP, PROFINET connectivity
  • Multiple programmable inputs and outputs to meet your I/O needs
  • Proven technology used to test millions of electronic devices
  • CTSnet LT software sets up easily and lets you connect to and manage other leak test instruments

Compact, Scalable Design Ideal for Integration into Machines and Stations

Here are some of the reasons why manufacturers choose the Sentinel MH:
  • Thanks to its small size, the Sentinel MH can be easily integrated into a test station—either in a single bay with manual fixturing, or in a multi-bay setup with automatic fixturing.
  • CTSnet LT software makes it fast and easy to set up the instrument.
  • Easily and cost-effectively lets you build out to the number of leak test channels you need over time.
  • Because it’s compact and the operator interface is on your PC, you can install it close to the part under test. This reduces system volume flow and provides a more accurate test.
