Finally, a compact economical pressure decay leak tester, with all of the integration features expected! Defender comes standard with Ethernet/IP. This is the best value of any pressure/vacuum decay leak tester on the market!

The UltraFlow V3 is LeakMaster’s latest mass flow leak testing innovation specifically designed to reduce cycle time and improve repeatability. Flow sensors ranges from 0-200 sccm up to 0-300 SLPM enable the UltraFlow to quickly test large parts yet versatile enough to test small parts.

The UltraFlow V3-RT is LeakMaster’s latest mass flow leak testing innovation with a user friendly mounting configuration. The separate Remote Interface allows the user to keep the interface very close to the operator while placing the leak test instrumentation wherever it is needed. Flow sensors ranges from 0-250 sccm up to 0-300 SLPM enable the UltraFlow to quickly test large parts yet versatile enough to test small parts.

For grueling production environments and automated leak test stations, the LeakMaster 700 Series Machine Mount is the ultimate configuration. It is available in pressure decay, differential pressure, and mass flow leak testing configurations.

You can trust the LeakMaster 700 Series Benchtop configuration in the most critical applications. It is the go-to configuration for laboratory environments, medical (device) leak testing, and manual leak test stations. The LeakMaster 700 series is available in pressure decay, differential pressure, and mass flow leak testing configurations.

For calibrated leak standards(leak orifices) LeakMaster is one of the top providers in the industry. LeakMaster takes great care to manufacture each leak standard to the specific flow rate and test pressure of each distinctive leak testing application.
