WebThe most common way of measuring the resistivity of a semiconductor material is by using a four-point collinear probe. This technique involves bringing four equally spaced probes in contact with a material of unknown resistance. The probe array is placed in the center of the material, as shown in Figure 1. Figure 1. WebFisherbrand Traceable Conductivity, Resistivity, and TDS Meters are ideal for measuring reagent-grade water to meet CAP, ASTM, NCCLS, and ACS specifications as well as for measuring conductivity in chromatography, biology, food, electronics, and water analysis. All readings automatically referenced to the international standard of 25°C.
