AMETEK PKm-354WC-SS

The Ametek PK2654WCSS PKII Pneumatic Deadweight Tester, with a range of 4 to 654 inH₂O and a stainless steel weight set, offers ±0.05% accuracy. This floating ball type tester is designed for user-friendly operation, safety, and optimal performance in both field and lab settings. Its self-regulating design automatically stabilizes weights, removing the need to adjust input pressure manually. Setting up the PK2-654WC-SS is straightforward: simply connect two tubes—one for the supply and one for the unit-under-test—level the PK II, and add the appropriate weights.
