Zaxis PD

Compact Pressure Decay Leak Tester

Zaxis PD Pressure Decay Leak Tester

The compact size and mounting orientation of the Zaxis PD enable close proximity to leak test fixtures, thereby reducing connection volume. Reducing test connection volume increases test sensitivity and decreases test times, yielding superior performance. All Zaxis leak testers have a small internal test volume. This optimized small internal test volume combined with integrated sensors and a 24-bit A/D converter enable Zaxis’ unparalleled performance. For multi-channel applications, consider purchasing multiple Zaxis PDs or look at the multi-channel Isaac HD.

Media Compatibility

Clean, dry, non-corrosive gasses

Media must be compatible with Aluminum and 316 stainless steel. Please contact us if there is a conflict and we can examine alternative solutions.

Calibration Accuracy

0.3% of full scale

High accuracy at a low price

Internal Volume

0.8 cm3

A 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.
