The Transforming Technologies SRM330 SRM330 Surface Resistance Travel Kit is the ultimate battery powered kit that is perfect for testing materials for electrical resistivity/resistance. It measures the resistance/resistivity according to EOS/ESD, CECC, ANSI, ASTM test procedures. It features built-in parallel electrodes for quick surface measurements and comes with two light-weight travel electrodes, which eliminate the cumbersome weights of standard kits. The Transforming Technologies SRM330 SRM330 Surface Resistance Travel Kits light-weight electrodes simulate the 5 lb. pressure necessary to measure resistance point-to-point or resistance-to-ground. This surface resistivity meter has an automatic test voltage selector; easy-to-read color coded readout screen and comes provided with a carrying case. It meets periods test requirements per compliance verification ESD TR53 and conforms to ANSI/EOS/ESD (S4.1, S7.1, S12.1, S2.1).
