Resistance Meters

Resistance meters are instruments used to measure the electrical resistance of a material or component. Resistance is a fundamental property of electrical conductors and is defined as the opposition to the flow of electric current. Measuring resistance is essential in the design, development, and maintenance of electrical circuits and systems.

Resistance meters use a variety of techniques to measure resistance, including the four-point probe method, the two-point probe method, and the bridge method. The four-point probe method is widely used for measuring the resistance of thin films and other materials with low resistance. This method uses four closely spaced probes to accurately measure the resistance of a material without being affected by the contact resistance between the probes and the material.
