Ralston Instruments' Hand Pumps are rugged and portable. Field tested calibration solutions with standard Quick-Test adapters which make connecting to pressure references and the device being calibrated a snap.
An outstanding solution for performing vacuum calibration in the laboratory or in the field where the pressure reference is attached to the pump with integral test gauge adapter. Not for use in Oxygen systems.
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.
Ideal solution for either differential pressure or vacuum calibration using precision test gauge or pressure calibrator as the pressure reference. Not for use in Oxygen systems.
Quick and efficient pneumatic field testing or pressure transmitters, gauges or switches is aided by an integral gauge adapter or for use with an external calibrator as the reference. Not for use in Oxygen systems.
Lightweight, high pressure source that can use oil or water as the test fluid.
