The LT-401 offers a semi-standard platform for leak testing. It is a versatile, general purpose machine that offers semi-automatic operation, outstanding productivity and is easily reconfigurable for changing future requirements. 

The LT-401 Series features pneumatic cylinders that accurately fixture and seal off inlets for testing as well as multiple sensors that make sure the test component is properly aligned in the LT-401. The new machines generate fast cycle times and offer automatic or 
semi-automatic functionality. 

Additional features of the LT-401 include a built-in PLC control with ladder logic creation, monitoring and storage capability. Programmable I/O and data collection enable stringent specifications to be met with ease and to be changed, should the necessity arise. History and monitoring functions record leak test results and system error data. 

The LT-401 has been designed for applications requiring pressure decay, vacuum decay and mass flow leak test systems to insure a high quality leak test operation.
