Flexibility and Simplicity

Zaxis’ instruments are built to meet an ever-changing manufacturing environment. The products that Zaxis has conceived in the past 30 years, first as IDS of Salt Lake City, Utah and today as Zaxis Inc, Salt Lake City, are still in use today throughout the world.

Simply Powerful

The Zaxis PD is the newest product from Zaxis, designed to meet today’s quality assurance demands. This tester has been designed for the do-it-yourself tooling person to mount on bench top work cells.

The compact size of the Zaxis PD enables it to be utilized in close proximity to test fixtures.  By reducing the test connection volume, the test sensitivity increases, and test times can be decreased.  Additionally, the internal volume of the Zaxis PD is less than 1 cubic centimeter. The small internal volume combined with integrated sensors and a 24-bit analog to digital converter allow Zaxis to offer a leak tester with the highest sensitivity.  The Zaxis PD is available for pressure or self-generating vacuum decay applications.  The Zaxis PD is configured for one channel.  For multiple channel applications multiple Zaxis PD’s can be mounted on automation for simultaneous testing.

This machine has been designed with the tooling engineer in mind. The unit allows wall mounting. Connections, electrical, air & communication are accessible from the bottom.  Be it bench top automation or full automation.



Dimensions6 x 7 x 6.5 in.A very small footprint enables you to maximize your lab or automation space.

Pressure: 0.00001 PSI

Mass Flow: 0.01 SCCM*

High sensitive ensures your parts are within your manufacturing specification.
Internal Volume0.8 cm3A small internal volume is often overlooked when purchasing a leak tester, but it is one of the most important specifications. A small internal volume minimizes testing variability such as thermal drift.
Pressure Range

0 – 15; 0 – 100 Positive Pressure

0 – 15 PSI Vacuum

With a wide range of pressures, you can tailor your leak tester to fit your specific application. Multiple test pressures on the same unit are available.
Calibration Accuracy0.3% of full scaleHigh accuracy at a low price
Time0.1 – 999.9 secondsThe Isaac HD can test rapidly or over a long duration depending on your specific application.
