Vernier calipers
Vernier Ver"ni*er, n. [So named after the inventor, Pierre Vernier.] A short scale made to slide along the divisions of a graduated instrument, as the limb of a sextant, or the scale of a barometer, for indicating parts of divisions. It is so graduated that a certain convenient number of its divisions are just equal to a certain number, either one less or one more, of the divisions of the instrument, so that parts of a division are determined by observing what line on the vernier coincides with a line on the instrument. [1913 Webster]

{Vernier calipers}, {Vernier gauge}, a gauge with a graduated bar and a sliding jaw bearing a vernier, used for accurate measurements.

{Vernier compass}, a surveyor's compass with a vernier for the accurate adjustment of the zero point in accordance with magnetic variation.
