Offered in pairs, the Model 832 and Model 846 Defined Surface Contact Area Electrodes in conjunction with the appropriate resistance meter enables point-to-point, resistance-to-ground and static dissipation of material and product to be measured. A single electrode is used to measure volume resistance. The Model 832 electrode assembly consists of 0.25” (6mm) square and 0.25 x 0.125” (6x3mm) rectangular conductive silicon rubber pads mounted to stainless steel electrodes that are attached to an insulated clamp exerting approximately 10 pounds (4.5kg) of contact pressure. The Model 846 has identical 0.375” (9.5mm) diameter
electrodes installed onto a clamp with adjustable contact pressure that is set to 20 lbs (9kg). To calculate volume resistivity the area of the smaller pad of the Model 832, 0.18cm2 , is divided by the thickness of the material in cm. For the Model 846 the 2.64cm2 area of the electrode is used in the calculation. The surface resistance of flat material and the outside surface of tubing are normally measured using the 0.25” x 0.25” (6x6mm) pad of the Model 832. To measure the inside surface resistance of tubing the 0.25” x 0.125” (6x3mm) pad is used.
