Perpendicular Verification Device

The Perpendicular Verification Device (PVD) rests on the lower platen of a compression machine.  It provides a fast and accurate verification of cylinder perpendicularity.  The PVD’s come in sizes to fit 2″ x 4″, 3″ x 6, 4″ x 8″ and 6″ x 12″ cylinders.  All sizes reach the test specimen while avoiding contact with the top and bottom retaining rings.

Each PVD comes with a gap measurement tool that quickly checks for gaps. Use the PVD-4NS (No Spacer) for putting your cylinder directly on the bottom platen. Use the PVD-4 if you are have a spacer below your cylinder.
