E-Meter

Common term for a device known as an "electropsycho-meter," invented by Volney Mathison in the United States. It measures galvanic skin response through changes in the electrical conductivity of the skin when the subject is emotionally aroused. The subject holds a handle in each hand, and strongly emotive thoughts cause a meter needle to register a dramatic change from zero. In the 1950s, the E-meter became an established part of the procedures of Dianetics and Scientology.

Use of the E-meter by the members of the Church of Scientology is explained in a series of books written by church founder L. Ron Hubbard.
