Proof Plane

Precision-Milled Conductive Disc: Features a 25mm diameter brass disc engineered with a smooth, burr-free perimeter to prevent localized corona discharge and ensure uniform charge sampling from conductive bodies.

High-Resistivity Insulating Handle: Incorporates a 200mm handle composed of advanced low-moisture-absorption polymers, providing a superior dielectric constant to prevent premature charge dissipation during the transfer process.
