A parallel electrode method with a shield connected to ground has been designed for electrical conductivity determinations in the multi-anvil apparatus. The advantages of the shield include avoiding electrical disturbance from the furnace, minimizing the temperature gradient, and reducing leakage current. This technique has been tested by electrical conductivity measurements on highly resistant alumina, Al<SUB>2</SUB>O<SUB>3</SUB>, and the measured conductivities are comparable to those of Duba  at 1 atm. We have also obtained reproducible results for olivine, wadsleyite and ringwoodite.
