The Ametek Crystal GaugeCalHP Pressure Comparator is a self-contained, precision hydraulic pressure comparator intended for the calibration of pressure gauges rated up to 15000 psi/1000 bar/100 MPa. You may fill the GaugeCalHP with your choice of water or oil.

The GaugeCalHP provides faster calibration than deadweight testers and most automated pressure controllers. You can calibrate most gauges, transmitters, pressure safety valves, sensors, and switches in less than ten minutes (5 to 10 test points, increasing and decreasing pressure) using the methods described in this manual.

The GaugeCalHP hydraulic comparator may be ordered as part of a Pump System, complete with a Crystal Pressure Indicator. GaugeCalHP Pump Systems include the most commonly used pressure fittings, seals, etc. All packaged in a carrying case with custom insert.
