LORESTA-GX has a expanded measuring range of 10-4~107 Ω.

Messung Loresta GX

The probe enables one-touch direct reading of [Ω], [Ω/sq.], and [Ω∙cm]. It has a special silicon mode for silicon wafer measurement and one-touch automatic measurement by new functions like Auto-Hold and Timer Mode. The accurate low resistivity meter based on 4 Terminal 4 Pin method. It ensures a high accuracy by MCP probes’ spring contact method which keeps pin pitch, pressure adn contact area on samples constant.
