The King Nutronics 3750 Portable Pressure Calibrator is a portable, self-contained pressure generator capable of producing and controlling calibration test pressures. The calibrator offers pneumatic and hydraulic pressure output from one pump and the pump head is rotatable up to 140 degrees with the bleed valve featuring a no-crush knob clutch. 

The reliable design of the King Nutronics 3750 Calibrator allows leak-free operation from vacuum to 10,000 psi. With the dual piston technology, technicians can control pressure changes by 0.001 psi test points and downscale pressure adjustments with bleed rates less than 0.1 psi / sec. This calibration hand pump is capable of operating in harsh environments, making it the U.S. Navy’s hand pump of choice for shipboard calibration on ships and submarines. The King Nutronics 3750 Portable Pressure Calibrator is constructed with stainless steel and advanced corrosion protection for testing under extreme envrionments. The unit has rugged impact-resistant controls, wear-resistant seals, and control surfaces.

The King Nutronics 3750 achieves calibration by comparing the device under test with a connected reference pressure indicator. The reference pressure or vacuum can be manually generated by squeezing the scissor-action handles on the pump and providing pressure adjustments, using the coarse and fine volume adjust knobs.
