PRF-914 High Resistance Miniature Concentric Ring

Accurately measure surface resistance of small areas

The PRF-914 Miniature E14 Probe Set accurately measures surface resistance of small areas up to 2.0x1014 ohms. It consists of a PRF-914 Concentric Resistance Fixture, dual shielded cables equipped with SMA and 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-914 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 standard. To estimate ASTM D-257 surface resistivity in ohms/square, multiply the fixture measurement by 10, i.e., add one decade.
