| eudiometer | <chemistry> An instrument for the volumetric measurement of gases; so named because frequently used to determine the purity of the air. It usually consists of a finely graduated and calibrated glass tube, open at one end, the bottom; and having near the top a pair of platinum wires fused in, to allow the passage of an electric spark, as the process involves the explosion and combustion of one of the ingredients to be determined. The operation is conducted in a through of mercury, or sometimes over water. Cf. Burette. Use's ediometer has the tube bent in the form of the letter. U. Origin: Gr. Fair, clear weather, fr. Fine, clear (said of the air or weather): cf. F. Ediometre. Source: Websters Dictionary (01 Mar 1998) |

A eudiometer is a device for measuring the change in volume of a gas mixture following combustion. In one form the device is a graduated cylinder, closed at the top end with the bottom end immersed in water or mercury. The liquid traps a sample of gas in the cylinder and the graduation allows measuring the volume of the gas. In the sealed end two platinum (chosen for its non-reactivity) wires are placed so an electrict spark can be created between them. ...
