LTI-06
The leak test instrument 6 (LTI-06) is a single-channel test system that operates on clean, dry shop air. It accurately tests for product leaks and is capable of testing Mass Flow, Pressure Decay/Change, & Leak/Flow with an accuracy of ± 1% Full Scale. The LTI-06 is designed for ease of use-it’s easy to set up and operate, affordable, comes with a 10″ color screen, and offers 30 Limit Tables for various pre-programmed testing via Pressure or Vacuum with ranges of 0-10sccm and 0-300slpm. Enclosed in a custom modular housing, the unit mounts easily to many surfaces and structures, making it a convenient and efficient solution for your testing needs.

LTI-250
The LTI-250A is a leak test instrument that can perform both mass flow and pressure decay tests. It is particularly useful in applications where two different tests need to run concurrently or when machine control is needed. The leak tester can store the leak rate detected and test results, which can be collected using the RS-232 port supplied on the unit.
