PRF-911 Concentric Ring Set

  • Used to design materials for Static Control and other Electrostatic Discharge (ESD) applications
  • Necessary for the Qualification and Verification of ESD Controlled Packaging Materials to meet current standards
  • Measures Surface Resistance per ANSI/ESD STM11.11
  • Measures Volume Resistance per ANSI/ESD STM11.12
  • Approximates Surface & Volume Resistivity per ASTM D-257
  • Incorporates a spring loaded, self-aligning center electrode feature to reduce calibration frequency
  • Its Dual Test Bed consists of an Insulated Test Surface for ANSI/ESD STM11.11 Surface Resistance measurements laminated to a Steel Test Plate used for ANSI/ESD STM 11.12 Volume Resistance measurements
  • Used with a wide range Resistance Meter and one 5 lb. Electrode. (Instrument and Electrode not included)
