Concentric Ring Probe Set

Measure Surface or Volume Resistance per ANSI/ESD STM11.11 and ANSI/ESD STM11.12
Designed originally for flat (planar) packaging materials, this unique portable test fixture will measure Surface and Volume Resistance of virtually any flat material in accordance with current industry standards. These include Surface Resistance per ANSI/ESD STM11.11, Volume Resistance per ANSI/ESD STM11.12, IEC 61340-2-3 and will approximate surface and volume resistivity measurements per ASTM D-257.
