Crystal Engineering CRYSTALCALHP-NPT-PSI

Ametek Crystal CrystalCalHP [CRYSTALCALHP-NPT-PSI] Pressure Gauge Calibration System.

The Ametek Crystal CrystalCalHP [CRYSTALCALHP-NPT-PSI] is a portable, high-speed pressure gauge and transmitter calibration system engineered for field professionals requiring both precision and efficiency. It features XP2i gauges rated at 1,000, 5,000, and 15,000 psi, and it outpaces deadweight testers by enabling complete 10-point calibration cycles in under 3 minutes.

Integrated with the GaugeCalHP hydraulic comparator, this system ensures unmatched performance in pressure calibration up to 15,000 psi (1000 bar / 100 MPa). Users can operate it with either water or oil, offering flexible media support for diverse calibration needs. Compared to automated pressure controllers, the CrystalCalHP reduces test time significantly and minimizes human error.

In combination with accessories such as FastCalXP software, footswitch, and CPF fittings, it supports calibration of gauges, pressure transmitters, safety valves, and switches—all within a portable and durable housing.

Incorporate this instrument within your Pressure Calibrators toolset to streamline your testing workflow.
