Mercury Four Point Probe
Four Dimensions, Inc. (Four Dimensions)
Based on decades of experience with needle four point probes and C-V, I-V Mercury probing stations, Four Dimensions developed a Mercury four point probe (patent pending). The liquid metal Mercury is used to form temporary electrical contacts at four terminals. These probes cause no damage to the sample and permit no contact pressure probing.
