Linear Leak Testers

Linear leak testers are ‘in line” defense systems for non-destructive leak testing used for empty containers such as water bottles, gallon jugs, and other plastic containers. Available as single or multi-test stations, these solutions are configured to test bottles “in-line” on a bottle conveyor system, as opposed to Rotary Leak Testers which operate as a rotary turntable. As containers move along a bottle conveyor system, a stationary or moving test head uses either vacuum decay or pressure decay to leak test each bottle.

These flexible solutions are ideal in a range of industries, from food and beverage to pharmaceutical. When tailored to the application, linear leak testers typically offer a more flexible and lower-cost approach for leak testing plastic bottles.
