The LTU8000 is the latest leak detector for “Uniloy” (flat-bed) and other indexed-conveyor deflash trimmers. It is an evolution of the LTU6000, which has become a de-facto industry standard fitted to new machines by the manufacturer. The LTU8000 updates the control panel with a new 10" color touchscreen and all-new electronics.

The connectors and voltages are compatible with the LT2, LTU2000 and LTU6000, so an existing installation can be upgraded simply by exchanging the front panel assembly. The panel assembly is also available on its own as a retrofit package, and the complete leak detector is available as a package for machines in the field — allowing consistent, high performance leak testing where existing solutions are aging, unreliable or inaccurate. Customers experience dramatic production efficiency improvements after upgrading, due to the elimination of incorrect bottle rejection and machine down-time.

The LTU8000 is the 24V DC version, for DC trimmer control systems. The closely related LTU4000 is the 110V AC version for AC trimmers — otherwise the two are identical.
