Gauge Comparators

Gauge comparators mount a reference gauge and the gauge under test on a common manifold, so both see the same pressure and can be read side by side.

Ashcroft, Fluke Calibration, Ralston and Crystal Engineering cover this range. This is the most efficient way to check a batch of gauges, because the pressure is generated once and compared directly rather than recorded against a separate standard. Specify pneumatic or hydraulic to match the gauges you service, and confirm the number and thread size of the test ports. A fine adjustment control is what lets you settle exactly on each cardinal point of the dial.
