PRF-914B High Resistance Miniature Concentric Ring Set

The PRF-914B Miniature E14 Probe Set accurately measures surface resistance of small areas up to 1.0x10¹⁴ ohms. It consists of a PRF-914B Concentric Resistance Fixture, dual shielded cables equipped with SMA and 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-914B is designed to work with a precision wide range resistance instrument, such as the Prostat PRS-801 Resistance System, and an insulated test bed.
