• Pressure Range: 0 to 5000 psi / 350 bar
The P-Series (System D) comparators are hydraulic screw pumps designed for easy, controlled, high pressure generation. Each comparator includes a 4 connection manifold, which can be used for the reference indicator, the device under test, a fine adjust, an isolation valve, or a fluid reservoir. The adjustable reference pressure port lets you set your reference gauge at the best viewing angle. Three models are available for hydraulic oil, water, or both. Each pump can be ordered alone or as a complete pressure system ready to use in a carrying case, including pump, hose, set of fittings, batteries, test leads, user manual, traceable calibration certificate, and Jofra or Crystal Calibration Equipment.
