The PRF-922B Miniature Two Point probe accurately measures point-to-point resistance of small areas. Like the PRF-912B Miniature Concentric Ring, the PRF-922B is capable of measurements up to 1.0x1012 ohms. Built-in distance stops provide consistent electrode to sample pressure for developing repeatable measurements. Use the PRF-922B to measure small material samples, hard to assess molded areas, edges of parts, tray or tape cells and other very small objects and surfaces. The assembly is supplied with replaceable conductive electrode covers to enhance contact resistance on irregular surfaces and composition materials. Thus, measurements may be made with either the gold plated electrode contacts, or via conductive rubber covers.

The PRF-922B is designed to be used 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, and an insulated test bed. When used with the supplied conductive rubber boots, it provides point-to-point resistance measurements in accordance with ANSI/ESD STM11.13.
