The LD-3 Dielectic Cell is designed for measurement of Dielectric Constant on rigid flat materials in accordance with ASTM-D150. For more information on the ASTM D150 Standard Test Methods for AC Loss Characteristics and Permittivity (Dielectric Constant) of Solid Electrical Insulation see ASTM D150 . Material up to 8cm or 3 1/8 inches with a maximum thickness of 1.1 cm or 7/16 inches can be used in the dielectric cell. The dielectric cell is made up of two electrodes. One electrode is fixed with a grounded guard ring and the other is movable via a micrometer. The micrometer allows precise measurement of electrode spacing. The grounded guard ring reduces fringe effects to improve measurements.

The dielectric cell has a usable frequency range from 50 Hz to 1MHz.
The three terminal electrical connections are made via GR-874 Connection on the fixed electrode side, optional BNC to GR-874 adapter is available, and banana connection on the movable electrode side.
