Making ultra-high resistivity measurements

November 3, 2016 Dale Cigoy

A fundamental property of insulators is resistivity. The resistivity may be used to determine dielectric breakdown, dissipation factor, moisture content, mechanical continuity and other important properties of a material. The volume resistivity of some insulators such as sapphire and Teflon can be as high as 1e16 to 1e18 ohm-cm.
