A colorimeter that uses a phototube or photocell, a set of color filters, an amplifier, and an indicating meter for quantitative determination of color.

An electronic device manufactured by the Church of Scientology at their Gold Base production facility.

Known as an "E-meter", it measures changes in the electrical resistance of the human body by inducing a tiny electrical current through it.

The face of the electropsychometer has a galvanometer that indicates changes in the subject's resistance. According to Scientology doctrine, the resistance corresponds to the "mental mass and energy" of the subject's mind, which changes when the subject thinks of particular mental images or engrams (unconscious, painful memories).

These concepts have no recognition among scientists outside of Scientology; the action of the E-meter is more commonly attributed to galvanic skin response, an effect used in lie detectors.
