Explore Solution by Leak Test

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, etc. Leaks always flow from higher pressure to lower pressure; leak testers use pressure to generate and monitor that flow.

Pressure Decay

Pressure decay is one of the most widely used methods of leak testing in manufacturing: pressurize the part, isolate it, and measure the drop.

Vacuum Decay

A cost-effective, non-destructive test for parts, packaging, and components — faster and more repeatable than a dunk test.

Mass Flow

Mass flow leak tests measure the flow rate through a part directly, an efficient method for higher leak-rate specs and flow verification.

Trace Gas

Helium, hydrogen forming gas, argon, or air tracer methods find leaks far smaller than pressure-based tests and give a quantitative leak rate for every part.

Chamber Leak Testing

A chamber test identifies leaks in sealed packaging or devices that have no accessible opening for a traditional leak test.

Mehdi Parsa

Great experience with Zaxis Inc. Zaxis Inc. is a highly reliable and professional engineering company. Their attention to detail, technical competence, and clear communication make them easy to work with. We are very satisfied with the collaboration and the quality of their work. I would happily work with Willam Dunkley again.

Dylan Bove

Dave Starrett has been very helpful showing me the Z5 and Z8 models on two separate occasions. He explained the in and outs of the tester in great detail and has even allowed my company to trail a unit to help us make our decision easier. Overall a great experience working with Zaxis.

Zaxis customer

Zaxis produces excellent and industrial grade durable metering pumps and provides great customer support. William Dunkley is awesome!
