Concetric Rings & Miniature Probes

For measuring surface and volume resistance according to ANSI/ESD STM11.11 and ANSI/ESD STM11.12, or point-to-point resistance in accordance with ANSI/ESD STM11.13, we have the right probe for your application. Our probe fixtures are designed to be portable and work with our wide range resistance meters.

PRF-911 Concetric Ring Set

Designed originally for flat (planar) packaging materials, this unique portable test fixture will measure surface resistance and volume resistivity of virtually any flat material in accordance with ANSI/ESD STM11.11, ANSI/ESD STM11.12 and ASTM D-257.
