INTRODUCTION
Thank you for purchasing a GaugeCalHP™ Pressure Comparator from Crystal Engineering. The GaugeCalHP is a self-contained, precision hydraulic pressure
comparator intended for the calibration of pressure gauges rated up to 15 000 psi / 1000 bar / 100 MPa. You may fill the GaugeCalHP with your choice of water
or oil.
Using this comparator for calibration is much faster than deadweight testers and most automated pressure controllers. The GaugeCalHP is so quick and easy
to use, it is ideal for calibrating those low cost gauges that are often overlooked for ISO9000 compliance.
In fact, 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.
Spend a few minutes to read this manual and learn how you can get the most benefit from your GaugeCalHP.
Note: We recommend using one of the following indicators with the GaugeCalHP.
