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

The PRF-912B is designed to work with a precision wide range resistance instrument, such as the PRS-801 Resistance System, or PRS-812 Resistance Meter or PAS-853B Wide Range Ohmmeter.
