Origin: [Gr. fair, clear weather, fr. fine, clear ( said of the air or weather) + -meter: cf. F. ediomtre.]
A eudiometer is a laboratory device that measures the change in volume of a gas mixture following a physical or chemical change.

The Standard Electrical Dictionary
A graduated glass tube for measuring the volumes of gases. In its simplest form it is simply a cylindrical tube, with a scale etched or engraved upon it, closed at one end and open at the other. The gas to be measured is collected in it over a liquid, generally water, dilute sulphuric acid in the gas voltameter, or mercury. Many different shapes have been given them by Hoffmann, Ure, Bunsen and others.
