Non-contact & Tapping

Probes with conductive tip-side coatings for non-contact and tapping (intermittent contact/semi-contact) mode electrical measurements (EFM, SKPM, SCM).

Au and Pt coatings are chemically inert (very stable towards oxidation and have a long shelf time) and have low resistance (provide ohmic contact with samples), whereas TiN and W2C coatings are hard and wear-resistant, but have a limited shelf life that depends mostly on humidity.
