Comparators & Hand Pumps

Field calibration of pressure instruments often requires a portable source of stable pressure. We have hand operated pneumatic pumps capable of pressures up to 4500 kPa / 650 PSI, with hydraulic options up to 1,000 Bar / 15,000 PSI. We also supply a wide range of regulators, valves, controllers and manifolds to allow precise pressure control of compressed air or nitrogen in your workshop or laboratory.
