Designed to Convert the PR-912B into a 2-Point Probe

The PRF-922A-B Adapter is configured to simply slide onto the PRF-912B and PRF-914B probes. It consists of a housing that fits over the concentric ring assembly and two spring loaded measurement probes.

A locking screw holds the adapter onto the host fixture and in contact with the miniature concentric ring test contacts.

Measure the Surface Resistance of Small Areas per ANSI/ESD STM11.13

When attaching the PRF-922A-B to the PRF-912B, you can measure the point-to-point resistance of small areas up to 1.0x1012 ohms. Use the adapter 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 spacing of the 2 electrodes allows for a measurement area of 0.32 inches (8.13mm). When used with the supplied conductive rubber boots, it provides point-to-point resistance measurements in accordance with ANSI/ESD STM11.13.

Best of Both Worlds for Small Parts

Having both concentric and 2-point fixtures provides maximum flexibility for measuring small areas and parts.

Spring Loaded Gold Plated Pins

The PRF-922A-B Adapter is designed with two spring loaded measurement probes and built in spacer to prevent excess probe pressure.

Conductive Rubber Covers for Better Contract

Removable conductive rubber probe covers are supplied to reduce contact resistance.
