Abstract
There is disclosed an electrical resistivity probe means adapted to cut and receive a sample of compliant test material therein. The probe means of the invention is useful, for instance, for the measurement of electrical resistivity of compliant materials having dispersed therein one or more electrically conductive fillers.
Claims10
An electrical resistivity probe means comprising, in combination:
- a tubular member having a rim adapted to cut into a compliant test material, said tubular member comprising a first electrode;
- a solid electrically insulative roof member bridging the bore of said tubular member and being displaced upwardly from the rim thereof, thereby to define a sample receiving chamber thereunder;
- a second electrode spaced from said first electrode;
- a solid electrically insulative floor member fixedly spaced under the rim of said tubular member and being adapted to support a sample of compliant test material thereon;
- and
- means to traverse the rim of said tubular member downwardly through a compliant test material stationed on said floor member.
