The Kelvin Probe F83511B0009G350 (item number 1154246) is designed for precise four-wire resistance measurements. The separate current and voltage paths in F83511B0009G350 support four-wire measurements in which lead and contact resistance have minimal influence on the result. The design combines a pitch of 3.5 mm / 138 mil with tip style 05 (Concave stepped) and a tip diameter of 2.75 mm. For F83511B0009G350, spring force is 300 cN at a nominal travel of 4 mm. The plunger in F83511B0009G350 is made of beryllium copper and is gold-plated.
