Persoz Pendulum Certified
Features
The Persoz pendulum is made from an open framework with an upper cross-bar that has two stainless steel balls inset to form a fulcrum. It also has a lower cross-bar that forms the pointer. The damping time, in seconds, for the oscillation amplitude of the Persoz pendulum to decrease from 12° to 4° is measured.
