High Quality Content by WIKIPEDIA articles! An E-meter is an electronic device used during Dianetics and Scientology auditing. The device is a variation of a Wheatstone bridge, which measures electrical resistance and skin conductance. It is formally known as the Hubbard Electrometer, after the Church`s founder, L. Ron Hubbard. Most of the Scientology concepts associated with the "E-meter" and its use are regarded by the scientific and medical communities as pseudoscience. The device itself is essentially a modified ohmmeter.
