The SRM500K is a digital surface resistance test kit designed to test all conductive, anti-static and static dissipative surfaces for electrical resistivity/ resistance according to EOS/ESD, CECC, ANSI, ASTM test procedures. It accurately and quickly measures resistance between two points (RTT) and surface to ground resistance (RTG). Suitable for factory audits and test lab evaluations, the Ohm Metrics SRM500K also measures ambient temperature and humidity.
