These pumps use compressed air to pump water or hydraulic fluid at high pressures through your system for leak testing.

With an accuracy of ±0.05%, these have the highest accuracy of all our test gauges.

With an accuracy of ±0.25%, these gauges are designed for critical processes that require precision.

These gauges have a glycerin-filled dial to reduce needle flutter for precise readings in high-vibration applications.

Commonly used to indicate clogged filters, these gauges display the difference between two pressure or vacuum measurements.

A band of green, yellow, and red provides a clear indication of changes in differential pressure.

Easier to read than U-tube gauges, these use an inclined scale to measure pressure or velocity changes in air applications. They are also known as manometers.

Use in medium-pressure applications up to 1,500 psi.
