Instrument Size (W x D x H): 17.5 x 12 x 8.5 in ( 440 x 300 x 215 mm)
Instrument Weight: 24 lb (11 kg)

For high pressure pneumatic calibrations this unit interfaces with hydraulic deadweight testers providing a rateless liquid-to gas separation. Driven by a pneumatic pressure source (nitrogen bottle) and controlled by needle valves, high pressure gas is balanced against the liquid in a hydraulic deadweight tester through a series of fluid traps.
* Note---since fluid mist may be transferred during operation we do not recommend this device for oxygensafe instruments using an oil operated deadweight tester. Test Port Adapters: 2 sets, 1/8, 1/4, 3/8 and 1/2 NPT or BSP
Gas Supply Connection: 1/4 NPT female

7 to 10 times faster than traditional gauge calibration methods
Automatic method reduces transcription / calculation errors
Crystal Engineering 's GaugeCalXP is a self contained precision hydraulic pressure generator intended for calibration of pressure gauges up to 10,000 psi. Pressure can be set very quickly and a comparison between a reference gauge (XP2I) and your test gauge can be done in less than 5 minutes for a 10 point calibration. The GaugeCalXP is much faster than deadweight Testers and costs much less.

• Automated and portable gauge / chart recorder calibration system
• Free language pack enables the program to be used in Chinese, Japanese, Korean, French and German
• Easy to use and install, wizards guide you through setup
