The PK II tester is a floating ball type, pneumatic deadweight tester. This model is engineered to offer user-friendly features, safe operation, and an optimal performance in the field or in the lab.

The AMETEK PK II Pneumatic Deadweight Tester is a primary standard that produces a pressure by applying force (weight set) over area (the ceramic ball and nozzle). The PK II 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 PK II 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 PK II tester features a quick-leveling system for field or lab setup. The unit may also be mounted on an optional tripod for more convenient setup. The tester may be operated with the cover opened or closed. Weights are located in foam-protective slots in the case.
