Ametek Pneumatic Deadweight Testers

The floating ball Ametek PK II & RK pneumatic deadweight tester is engineered to offer user-friendly features, safe operation, and an optimal performance in the field or in the lab. Ametek's pneumatic deadweight testers produce 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.
