What does gaussmeter mean?
A gaussmeter is a scientific instrument used to measure magnetic flux density, the strength of a magnetic field at a particular point. The reading is conventionally expressed in gauss, a unit named after the German mathematician and physicist Carl Friedrich Gauss; in SI-based work, the equivalent quantity is usually expressed in teslas. A gaussmeter is useful whenever a technician needs a numerical check of the field surrounding a magnet, electromagnet, motor component, or another magnetic assembly. It can also be used to compare readings at different positions. The word is technical and relatively uncommon, although it is also written as "gauss meter." The instrument belongs to the broader family of magnetometers, while its name and scale traditionally emphasize magnetic flux density measured in gauss. Its practical value lies in turning an invisible field into a standardized, repeatable measurement, allowing magnetic equipment to be positioned, calibrated, and checked with confidence.
nounAn instrument for measuring magnetic flux density, especially the strength of a magnetic field at a particular point.
- An instrument for measuring magnetic flux density, usually displaying its reading in gauss.
"The technician checked the gaussmeter before positioning the magnet over the sensor."
"The reading on the portable gaussmeter confirmed that the field was within the specified range."
"The museum uses a gaussmeter to check the strength of the magnetic field surrounding its display case."
The regular plural is used when referring to multiple instruments.
"The technician compared readings from two gaussmeters."
Named for Carl Friedrich Gauss, the unit and the instrument that measures it form one of science's neatest eponyms.

Etymology of gaussmeter
Gaussmeter is a compound of gauss, the unit of magnetic flux density, and -meter, a suffix denoting a measuring instrument. The gauss was named in honour of Carl Friedrich Gauss, the German mathematician and physicist, while related vocabulary forms include Gaussian and Gauss's law.
How gaussmeter is actually used
This is a technical and relatively uncommon term, also written as "gauss meter." It belongs to the broader family of magnetometers, but it specifically emphasizes measurement of magnetic flux density.
Easily confused with gaussmeter
A gauss is a unit of magnetic flux density, whereas a gaussmeter is the instrument used to measure that quantity.
