The Multi Height Probe combined with the ResTest Test Unit is a great system for use in measuring a wide range of materials and sample sizes when the greater measurement range of the RM3000 Test Unit is not necessary.
Four-Point-Probes offers 4 point probe equipment for measuring the sheet resistance and bulk (volume) resistivity of materials used in the semiconductor industry, universities, and in materials science including thin films, wafers, ingots, and other materials and conductive coatings.
