Conductivity, different testing fixtures can meet the testing requirements of different materials. Testing fixtures can be selected according to product and testing project requirementsThe dual electric measurement digital four probe tester uses linear or square four probe dual position measurement. The instrument design complies with the physical testing method standards for single crystal silicon and references the United StatesA.S.T.M

Standard. By using the transformation of current probes and voltage probes, two electrical measurements are taken, and the data is analyzed using dual electrical measurements. This automatically eliminates the influence of sample geometry, boundary effects, probe misalignment, and mechanical drift on the measurement results. Compared with single electrical measurement linear or square four probe probes, it greatly improves the accuracy, especially suitable for testing micro areas with oblique four probe probes.
