It’s leak detection simplified. LeakMaster’s 700 series is not only extremely fast, it’s repeatable, and, best of all, it’s user friendly. Add the fact that the 700 series is configurable for pressure decay leak testing, mass flow leak testing, or differential pressure decay leak testing and you can be confident you have one of the most versatile precision air leak test instruments available.

Optional Ethernet/IP module for seamless integration with Allen Bradley EtherNet/IP or other compatible devices, eliminates I/O wiring, reduces start-up time and hardware cost. Provides ultimate control and the ability to capture valuable leak rate data for data collection systems, critical for today’s production environment.



The LeakMaster 700 Series Benchtop configuration is the go-to configuration for labratory environments, medical leak testing, and manual leak test stations.

The LeakMaster 700 Series Machine Mount configuration is for grueling production environments and automated leak testing machines.

Available Leak Test Modes

Leak testing is determining whether a product passes a specified leak limit. Leaks occur when a gas or liquid can escape a product caused by holes, cracks, insufficient seals, or permeable areas in a product due to defects in the manufacturing process. There are several different types of leak testing technologies available that can be implemented for specific applications. The chart below shows the different test types available for the 700 Series leak test instrument.

Pressure Decay
Vacuum Decay
Mass Flow
Differential Pressure
Metered Volume
