Generate either 125 psi (8.6 bar) pressure or 23 inHg (584 mmHg) vacuum with the same pump. Unique design allows the user to convert from pressure to vacuum by simply twisting a knob, even with gloves on. Two outlet ports allow connection to reference pressure gauge or pressure calibrator as well as device under test, eliminating a tee. Large-volume, fine-adjustment piston provides precise control, even at very low pressure.

Precisely vent pressure with soft-seated bleed valve. Generate either a vacuum or a pressure for calibrating low pressure, or vacuum instrumentation using an external pressure calibrator.
