Concentric Ring Set

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)
