The PK II Pneumatic Deadweight Testers are self-regulating, primary standards with a
pressure capacity of 104- 254-, 304- and 854-inches H
2
O. These instruments operate on
the deadweight principle using only fundamental units of force and area. Pressure equals
the weight force divided by the effective area of the ball.
All PK II Testers are shipped with tester and weight contained within a carrying case. The
instrument is available with accuracies of +0.015%, +0.025% or +0.05% of indicated read-
ing with stainless steel weights.
