An instrument for measuring the rise and fall of rivers.

1. An instrument used for the measurement of magnetic flux or the lines of magnetic force arising from and found in the vicinity of a magnetized body.
2. A meter that measures magnetic flux by the current it generates in a coil.

An instrument designed specifically for the measurement of low temperatures.

An instrument for testing taste sensation by applying an electrical stimulus to the lingual mucosa.

1. An instrument that detects, measures, and determines the direction of a small electric current.
2. An instrument that measures a small electric current by measuring the mechanical motion derived from electromagnetic or electrodynamic forces produced by the current.

Galvanometers can be used directly as ammeters, and are the core element of many ohmmeters and voltmeters.

The art or process of measuring the force of electric currents.

A gauge for measuring laughter

A reference to the measurement of an interval of time in relation to the history of the Earth and by using absolute or relative dating techniques: Geochronometric research involves the assessments of geologic time by scrutinizing isotopic radioactive decay.

An extension of geometry conceived as taking time into account as the fourth dimension; the geometry of space-time: Geochronometry uses faultless calculations of geologic time, as through isotopic-radioactive decay or radioactive elements or minerals.

1. Pertaining to, or according to the rules or principles of, geometry.
2. Determined by geometry; as, a geometrical solution of a problem.

Geometrical is often used in a limited or strictly technical sense, as opposed to mechanical; therefore, a construction or solution is geometrical which can be made by ruler and compasses; that is, by means of right lines and circles.

1. In a geometric fashion.
2. With respect to geometry.
3. According to the rules or laws of geometry.

1. The branch of mathematics that deals with points, lines, surfaces, and solids, and examines their properties.
2. A branch of mathematics that is concerned with the properties and relationships of points, lines, angles, curves, surfaces, and solids.
3. In nuclear medicine, any of the various arrangements between a radioactive source and a detector that affects the accuracy of counting or measurement.

1. The direct or indirect measurement or approximation of the temperatures at which geologic processes take place or have taken place.
2. The study of the earth's heat and temperatures, and their effects on geologic processes.
3. The study of the earth's heat and subsurface temperatures.
4. In geology, a mineral or aggregate of minerals whose presence defines the temperature range of limits within which the minerals were formed; also known as a geologic thermometer.
