Model 831 Volume Resistivity Test Fixture


The Model 831 is designed to perform volume resistivity measurements per ASTM D991 Rubber Property Volume Resistivity of Electrically Conductive Antistatic Products.

This test method utilizes the measurement of current flow through a material and the voltage drop across a section of the material to calculate the volume resistivity in ohms-cm. The test fixture, fabricated from nickel-plated steel and Delrin, is designed to measure standard 3″ x 5″ test samples.

  • Conforms to ASTM D 991 requirements
  • Measures standard 3″ x 5″ samples
  • Plated steel & Delrin construction
  • Use with any V/I instrument
