262A Surface Resistivity Meter
Description
Model 262A provides convenient, accurate testing of resistance/resistivity of products ranging from ESD shielding bage to static dissipative mats to conductive work surfaces. The LED decade display minimizes the chance of reader error. Resistivity (W / n ) is measured by placing the 262A’s parallel electrode rails completely in contact with a flat sample. The geometry of the electrode assembly is such that current flow from one rail, across the sample, to the other rail is a direct indication of the sample’s resistivity, which is read on the LED display. In the resistance-measuring mode, current flows from ground through the resistive material to the measurement electrode.
