Crystal Engineering GaugeCalHP Pressure Comparator Pump

The GaugeCalHP is a portable, self contained, hydraulic pressure generator for calibrating pressure gauges, transmitters, sensors, and safety valves.  

• Pressure to 15 000 psi / 1000 bar / 100 MPa 
• Vacuum to -12.5 psi / -0.8 bar / -86 kPa
• Faster than any deadweight tester and most automated pressure controllers

Use without fluid to generate up to 400 inches H₂O (995 mbar) to within 0.01 inches (0.025 mbar). Makes calibrating Differential Pressure Transmitters easy.

• Easily test large size gauges with the unique pivoting manifold
• Quickly bleed air and capture fluid with the no mess drip tray
• Gauge-Safe integral venting system prevents damage to mechanical gauges
• Use with water, light oil or air

• Field and laboratory pressure source
• Low cost replacement for hydraulic ram screws on deadweight testers
• Ideal for calibrating low cost gauges that are often overlooked for ISO9000 compliance
• Continuous vacuum to pressure generation is great for compound range devices

Two pressure ports are provided. Connect a reference grade gauge on one port (we recommend an XP2i Digital Pressure Gauge) and the gauge to be tested on the second port. Rotate the handle clockwise until the desired pressure is generated. Then, compare the displayed pressure values between the reference gauge and the gauge under test.

Pressure can be set very quickly and precisely. Gauges can be calibrated in less than two minutes with 5 to 10 test points, increasing and decreasing pressure. The comparator can be filled with oil, water, or even air, allowing for clean and safe calibration of most gauge types.
