Comparator Pump - 1400 Bar Hydraulic Oil

Bench mounted comparator pumps provide a stable source of pressure when calibrating pressure gauges or pressure transmitters against a known reference source such as a 0.25% accuracy bourdon tube test gauge. The test instrument and reference instrument are mounted on the ports either side of the fluid reservoir and pressure is increased or decreased by winding the priming pump handle in or out.

This comparitor will also require a master reference instrument to be used, we suggest either a master test gauge, digital test gauge  or precision pressure transmitter depending on the accuracy of the instruments under test.

If the deadweight tester is to be used to calibrate pressure instruments used on oxygen or degreased applications, we suggest an oil/water separator is used.
