The Hitachi Kokusai VR 120 S Resistivity Test & Probe is a test and probe instrument for measuring resistivity and sheet resistance.[2]
A resistivity test and probe system measures electrical properties by contacting a conductive sample and determining resistivity and sheet resistance.
A four-point resistivity system separates current injection and voltage sensing so the measurement is based on the sample rather than on contact resistance.
The instrument is used for resistivity and sheet resistance measurement on wafers from two to twelve inch.[2]
