The SRM Probe Head is a plastic bodied four point probe head which is applied by hand. The connection to the probe head from the SRM-232 electronics is via a female RJ45 connector which is the same type of connector used for Ethernet connections.
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.
