Faraday Cup

  • Product No:Model 231
  • Manufacturer:Electro-Tech System,Inc

The Model 231 Faraday Cup measures charge on materials, devices and assemblies when used in conjunction with the ETS Model 230 or equivalent nanocoulomb meters. The Model 231 includes a double-walled shielded cup, cover, 36″ BNC-BNC cable and conductive foam pad. The Faraday cup meets the requirements of triboelectric charge generation test procedures to evaluate the antistatic characteristics of material and components in accordance with industry and military specifications. The optional holding fixture allows precision angle adjustment for tests utilizing inclined plane methods such as those specified in ESD STM 11.12 and EIA-541.
