SPECIMENS-PROBES MOUNTING HOLDER FOR FOUR-PROBE CONDUCTIVITY MEASUREMENT

摘要

PURPOSE: A specimens-probes mounting holder for four-probe conductivity measurement is provided to increase the accuracy of measurement by minimizing a contact size of a sample and a probe. CONSTITUTION: A specimen(1) is located on a lower support(10). A four-probe installation holes(22) are formed in upper support(20) at the fixed interval. A support fixing units(30) is separated by as much as set interval between the upper support and the bottom. 4 probes(40) comprises a body of the rod-shape and a head(42) of the sharp end form. The body installs to the probe installation hole. The head of the sharp end form is formed in the lower part of the body. An elastic members(50) pushes the head in the direction of the down support stand.
