SKP Probes
Scanning Kelvin Probe (SKP) probes measure the Volta potential of a sample relative to the probe material without touching the surface. On the BioLogic M470, this non-contact technique is widely used to study atmospheric corrosion, coating delamination, galvanic coupling and work function differences across metals and semiconductors. Each probe uses a tungsten electrode inside an air-gap shielded brass casing, with an Electro-Speed connector. Two sizes are offered. The 500 µm probe (part U-SKP370/1) has a nominal length of 80 mm, and the 150 µm probe (part U-SKP-150) is 50 mm long. The smaller tip gives finer spatial resolution, while the larger one suits faster surveys over bigger areas. Probes are supplied individually, so it is easy to keep a spare on hand. Australia's coastal climate makes corrosion research a priority for infrastructure, defence and transport, and SKP is one of the most informative tools for that work.
