King Nutronics 3750

Portable Pressure Calibrator

The King Nutronics Model 3750 is a portable hand pump that generates pneumatic pressure from 0 to 500 psig and hydraulic pressure up to 10,000 psig with the HPDX configuration. It provides pneumatic pressure control resolution of ±0.001 psi and hydraulic pressure control resolution of ±0.1 psi. The pump supports combined pneumatic and hydraulic operation using distilled water as the recommended hydraulic fluid. It includes a pressure relief valve adjustable from 150 psi to 10,100 psi for controlled pressure reduction.
