PROSTAT PRF-922B
MINIATURE TWO-POINT PROBE SET
THIS TWO POINT PROBE ACCURATELY MEASURES POINT-TO-POINT RESISTANCE OF SMALL AREAS 0.9 X 1012 OHMS.
. Measures point-to-point surface resistance of small areas up to 0.9x1012 ohms.
. Measurement Area: 0.25" (6.35mm).
. Spring loaded contact pins.
. Includes one (1) each spare contact pins and conductive rubber boots for measuring surfaces in accordance with ANSI/ESD STM11.13.
The PRF-922B Miniature Two Point probe accurately measures point-to-point resistance of small areas. Like Prostat's 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 Prostat PRS-801 Resistance System, 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.
