PRF-912 Miniature Concentric Ring

The PRF-912 Miniature E12 Micro Probe Set accurately measures surface resistance of small areas up to 1.0x1012 ohms. It consists of a PRF-912 Concentric Resistance Fixture, shielded cable equipped with BNC connectors, and a BNC to male banana instrument adapter. The optional PRV-913 Verification Fixture is designed to confirm the proper operation of the PRF-912 and high resistance PRF-914 Miniature Probe Sets.

The PRF-912 is designed to work with a precision wide range resistance instrument, such as the PROSTAT PRS-801 Resistance System, and an insulated test bed. It provides surface resistance measurements in ohms per ESD S11.11 Surface Resistance test standard. To estimate ASTM D-257 Surface Resistivity in ohms/square, multiply the fixture measurement by 10.
