The Series PCHP pneumatic calibration hand pump from Dwyer Instruments comfortably sources pressure and vacuum to check calibration of gauges, switches, transmitters and recorders. The ergonomically designed, contoured cushion handles provide extra comfort while preventing the pump from sliding. An oversized check valve offers smooth operation throughout the output range, and dual O-rings on all pistons prevent leakage. Output range is -0.945 bar to 40 bar (-28 in. Hg to 600 psi). Materials of construction include stainless steel fittings, anodized aluminum housing, plastic/rubber handles and Nitrile O-rings.
