[puh-ten-shee-om-i-ter] /pəˌtɛn ʃiˈɒm ɪ tər/
a device for measuring electromotive force or potential difference by comparison with a known voltage.
(chem) (of a titration) having the end point determined by a change in potential of an electrode immersed in the solution
an instrument for determining a potential difference or electromotive force by measuring the fraction of it that balances a standard electromotive force
a device with three terminals, two of which are connected to a resistance wire and the third to a brush moving along the wire, so that a variable potential can be tapped off: used in electronic circuits, esp as a volume control
1868, a hybrid formed from comb. form of Latin potentia “power” (see potential) + Greek-derived -meter.
- Potentiometric surface
potentiometric surface (pə-těn’shē-ə-mět’rĭk) A hypothetical surface representing the level to which groundwater would rise if not trapped in a confined aquifer (an aquifer in which the water is under pressure because of an impermeable layer above it that keeps it from seeking its level). The potentiometric surface is equivalent to the water table in an […]
