Measure the Surface Resistance of Small Areas per ANSI/ESD STM11.13 and IEC 61340-4-10
The PRF-922B Miniature Two Point probe accurately measures point-to-point resistance of small areas up to 1.0x1012 ohms. Use the PRF-922B to measure small material samples, hard to access 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 0.325 inches (8.26mm) on planar material. When measuring molded parts, the PRF-922B allows you to measure a diameter of 0.491" (12.46mm). When used with the supplied conductive rubber boots, it provides point-to-point resistance measurements in accordance with ANSI/ESD STM11.13 and IEC 61340-4-10.

Enhance Contact Resistance with the Included Conductive Rubber Boots
The PRF-922B 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 rubber boots resistance is less than 2 ohms, minimizing contact resistance and providing accurate measurements.

Additional rubber boots can be ordered using the part number PRF-MR10.

Easy and fast Connection to any of Prostat's Resistance Meters
The miniature 2-Point Resistance Probe is supplied with a single 5 foot shielded cable consisting of a 4mm BNC connector on one end, and a standard jack connection on the other for easy connection to any of the Prostat resistance meters.

Spring Loaded Gold Plated Pins
The PRF-922B Mini Point-to-Point Probe is designed with 2 spring loaded, gold plated electrodes. The built-in distance stops provide consistent electrode to sample pressure for developing repeatable measurements.

Convert it into a 1-Point Probe
By removing the non-conducting pin from the PRF-922B, you can convert the fixture into a single point probe for convenient 1-point resistance measurements.
