Test Types

A leak test is used to determine if an object, product, or system functions within a specified leak limit. Leaks occur when gas or liquid flow through an object via an imperfection or manufacturing defect such as holes, cracks, weak seals, ect. Leaks always flow from higher pressure to lower pressure; leak testers use pressure to generate and monitor that flow.


Zaxis’ instruments are built to meet a dynamic manufacturing environment. Quality, speed, and repeatability are at the forefront of the Zaxis design process. The compact size of the Zaxis testers enables them to be utilized in close proximity to test fixtures. A small internal volume, when combined with integrated sensors and a 24-bit analog to digital converter, allow Zaxis to offer the highest sensitivity on the market.


We stand behind our products and they are built to last. This makes the relationships we build with our customers just as important as the products themselves. With over 35 years of leak testing experience, our service team is ready to troubleshoot and address all of your concerns.
