Sentinel I28 Leak Detection System

  • Sentinel I28 Leak Test Device

Cincinnati Test Systems’ Sentinel I28 is one of the most advanced multi-functional test instrument on the market. This single-station air flow and leak detection system features a standard valve manifold design that is tested for over 40,000,000 cycles. This manifold is paired with a new high performance pressure transducer that reduces test cycle times and improves accuracy and repeatability. A high contrast 24 bit color TFT display provides XY graphing for pressure, loss, or flow.

Sentinel I28 Leak Testing Technologies

The Sentinel I28 leak detection system is configurable for a variety of pressure decay testing or mass flow testing requirements. It provides storage for up to 99 pre-programmed test sequences, and features a “Parent Program” that holds a customized test sequence for your multi-test application.

The test program can be selected via keypad, RS232, or binary. Test result evaluation is user-selectable (fail/pass/fail, etc.). The output format for test results can be configured to meet your needs.

Pressure Decay/Mass Flow Test Options


Selectable Test Parameters

  • Quick test
  • Test pressure level compensation (selectable on/off)
