P5521 and P5522 Liquid-to-Liquid Separators

These liquid-to-liquid separators connect directly to the test port of a hydraulic deadweight tester or comparison test pump. A flexible diaphragm separates the fluids, protecting the calibrator from contamination, and allows calibration of the device in its specific working fluid.

P5543 Angle Adapter

To calibrate gauges with the pressure connection on the rear (for example, panel mount gauges) in their correct operating position, an angle adaptor should be used. The angle adapter uses the standard gauge adapters and positions the gauges at 90º. The maximum working pressure of this unit is 10,000 psi (700 bar).

P5544 Two Gauge Stand

This adapter mounts directly to the test port of the calibrator and allows for the calibration of two instruments at the same time, or the connection of a reference test instrument. Maximum working pressure is 10,000 psi (700 bar).

P5551 Pointer Remover/Punch

This tool is designed to quickly remove and consistently refit the pointer of a pressure gauge.
