The AMETEK HK Pneumatic Deadweight Tester is a primary standard used to calibrate pressure and differential pressure gauges, transmitters, transducers, recorders and controllers, which can provide a reference pressure in process control applications.The AMETEK HK Pneumatic Deadweight Tester is a primary standard that produces a pressure by applying force (weight set) over area (the ceramic ball and nozzle).
The HK tester is NIST traceable and accurate to ±0.015% using stainless steel weights calibrated to International standard gravity at 9.80665 m/s2 or local gravity as specified. The HK tester is self-regulating with accuracy independent of the operator. The tester utilizes a virtually frictionless ceramic ball floating on a layer of air within a stainless steel cylinder.
The HK tester features a quick-leveling system for lab setup. The unit may also be mounted on an optional tripod for more convenient setup. Weights are located in foam-protective slots in the case.
