AMETEK STC provides the world’s only ball-type deadweight testers, where the ball and weights float on a thin film of air, which is virtually frictionless.
This design eliminates the necessity to rotate the weights during testing and allows the user to concentrate on the instrument itself.
The testers are manufactured and sold under the brand M&G (Mansfield & Green) and are engineered to offer user-friendly, safe operation, in the field, or in a lab. Both pneumatic and hydraulic deadweight testers are available.
PK II Deadweight Testers
