Pneumatic Cylinder Hand Pumps

Precise Low Pressure Calibration

Economical solution for calibration of low pressure differential transmitters. Simple direct-acting pump action with fine adjustment piston makes an easy and precise pressure setting. Not for use in Oxygen systems.

Pneumatic Cylinder Hand Pumps

The ideal solution for very precise low-pressure calibration or differential pressure testing using an external pressure calibrator as the reference
