This product is no longer in stock
The Model 12962A sample holder is designed to allow accurate impedance tests of solid materials to be performed at room temperature. The sample holder comprises of two parallel electrodes, one of which is fixed in position and the other which can be moved into contact with the sample by adjustment of a micrometer. The sample holder makes use of guard ring and reference techniques in order to improve accuracy by reducing &ldquo:fringing&rdquo: effects at the edge of the sample. The standard electrode provided is 20mm diameter.
