(Greek: measure)

dysmetria
1. The inability to fix the range of a movement in muscular activity.

Rapid and brusque movements are made with more force than necessary.

2. The inability, in the performance of a movement, to judge direction and distance, seen particularly when the patient attempts to touch his nose or the examiner’s finger with his finger, or his knee with his heel.

The movement, while generally in the right direction, either veers to the side of the target or overshoots (hypermetria).

dysmetropsia
The inability to visualize correctly the size and shape of things.
dyssymmetry
A lack of symmetry or something that has two sides or halves which are the same or very close in size, shape, and position.
econometrics
The branch of economics concerned with the application of mathematical economics to economic data by the use of statistical methods.
ecotelemetry
Measurement and transmission of vital information; biotelemetry.
eidonometer
An instrument for measuring visual acuteness of the perception of form.
eidoptometry
Measurement of visual perceptions.
electrogoniometer
1. An electrical device for measuring angles of joints and their ranges of motions.
2. An instrument used to measure positions of flexion (the bending of an arm, leg, or other joint) and the extension of a hinge joint.
electrogustometry
1. An assessment of the integrity of the sense of taste by using graded electrical stimuli that is applied to the lingual mucosa or tongue.
2. A measurement which tests the degree of the sense of taste by applying a direct electrical current to various points on the tongue.

An anode or electrode to which a major flow of electrons takes place and that is applied to different points on the protruded tongue and the electric current necessary to produce an acid taste is measured and recorded.

electromanometer
1. An apparatus used to gauge or to measure the pressure of gases or liquids which uses an electric signal as the indicator.
2. An electronic instrument that is used to gauge the pressure of liquids or gases or which is used for measuring the pressure of gases or liquids by electronic methods.
electrometer
1. A sensitive device for measuring extremely low voltages by means of the forces of attraction and repulsion between charged bodies on plates or wires.
2. An instrument for detecting or determining the magnitude of a potential difference or charge by the electrostatic forces between charged bodies.
3. A fundamental instrument in which potential is measured by the attraction between two oppositely charged disks.
4. An instrument for measuring the quantity or intensity of electricity; also, sometimes, and less properly, applied to an instrument that indicates the presence of electricity; also called an electroscope.
5. An instrument used to determine fluctuations in electrostatic potential difference between charged electrodes due to radiation.
electrometrogram
1. An electrical record of a locomotive regarding its speed and the number and duration of its stops.
2. In medicine, an instrument which can record changes in the electrical potentials of uterine muscles.
electrophotometer, photoelectric colorimeter
A colorimeter that uses a phototube or photocell, a set of color filters, an amplifier, and an indicating meter for quantitative determination of color.
electropsychometer, E-meter (s) (noun)
An electronic device manufactured by the Church of Scientology at their Gold Base production facility: "Known as an "E-meter", the electropsychometer 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 person's resistance. According to Scientology doctrine, the resistance corresponds to the mental mass and energy of the subject's mind, which changes when the individual thinks of particular mental images or engrams (unconscious, painful memories)."

"These concepts are not validated by other scientists outside of Scientology; the action of the E-meter is more commonly attributed to galvanic skin response, an effect that is used in lie detectors."

electroradiometer
1. An electroscope (device for detecting the presence of an electrostatic charge) of any of several designs suitable for the measurement of ionizing radiation arriving through the air.

Typically a microscopic, electrically conducting fiber (for example, silvered quartz) is suspended in a chamber, close to and connected with an insulated wire support where an electrostatic charge is applied, and similar charges deflect the fiber away from the support, the movement being monitored with a microscope and scale.

As the radiation of interest ionizes the enclosed gases, a slow discharge occurs, and the fiber retreats toward its resting position, the rate of movement indicating the intensity of the radiation.

2. A modified electroscope designed for the differentiation of radiant energy or energy contained in light rays or any other form of radiation; such as, X-rays or gamma rays.

An electroscope is an instrument for detecting the presence of electricity, or changes in the electric state of bodies, or the species of electricity present, by using pith balls, etc.
