An Electropsychometer, abbreviated to E-meter, is a modified ohmmeter used during Dianetics and Scientology auditing. The device is a variation of a Wheatstone bridge, which dates to 1833 and measures electrical resistance and skin conductance. It is formally known as the Hubbard Electrometer (although it is not an electrometer as usually defined) after the sect’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, and the E-meter has never been subject to clinical trials.
The sect restricts the use of the E-meter to trained Scientologists, treating it as “a religious artifact used to measure the state of electrical characteristics of the ‘static field’ surrounding the body”.
The meter, when used by a trained Scientologist, is claimed to reflect or indicate whether or not a person has been relieved from spiritual impediment of past experiences. Officials within Scientology assert that the E-meter is intended for use only in sect-sanctioned auditing sessions and is in itself not a curative or medical device. The E-meters used by the Church of Scientology are manufactured by Scientologists at their Gold Base facility.
It would be the PERFECT conversation piece … but alas, not for $8 grand.
