The floating ball Ametek PK II pneumatic deadweight tester 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 produces pressure by applying force (weight set) over area (the ceramic ball and nozzle). While in operation, the ball and weights float freely, supported only by a thin film of air which is virtually frictionless. This eliminates the necessity to rotate the weights during testing and allows the user to concentrate on the instrument calibration.

The Ametek PK II pneumatic deadweight tester is self-regulating with accuracy independent of the operator. The Ametek PK II pneumatic deadweight tester has a built-in flow regulator that automatically adjusts the input air flow to maintain the ball and weights in a float position. The regulator also compensates for variations in pressure from the air supply. These features of the Ametek PK II pneumatic deadweight tester eliminate the necessity of having to continually adjust the supply during the test and provides for an easy up and down scale calibration.

The setup for the Ametek PK II pneumatic deadweight tester is completed by simply connecting two tubes, one for the supply and one for the unit-under-test, leveling the PK II, and adding the appropriate weights. Operation is fast and efficient with no valves to adjust and no regulation needed between set points. Pressure regulators are not required if the air supply is within the Ametek PK II pneumatic deadweight tester's operational requirements.

The Ametek PK II pneumatic deadweight tester is NIST traceable and accurate to ±0.05% (optional accuracy up to ±0.015%) using stainless steel weights calibrated to International standard gravity at 9.80665 m/s2 or local gravity as specified. The Ametek PK II pneumatic deadweight tester's test fluid is nitrogen or instrument quality air complying with the ISA Standard S7.3. This fluid is non-contaminating to virtually all processes, thus eliminating the need to clean instruments after calibration and before use.
