摘要： This invention relates to a method and apparatus for measuring ethanol vapour concentration. Both methods and the apparatus determine the gradient of the initial steady state part of the output of a fuel cell prior to a peak height being reached and use that determination to generate an ethanol vapour concentration signal.

摘要： A fuel cell sensor (10) comprises a main body (11) in which are mounted working electrodes (12), counter electrodes (13) and respective contacts (14 to 17). The working electrodes (12) are mounted facing each other to define a sample space between them. The electrodes (12) are electrically interconnected in parallel as are the two counter electrodes (13). This arrangement makes it possible to provide a very large working electrode surface area for a small volume sample space (22).
摘要翻译： 燃料电池传感器（10）包括其中安装有工作电极（12），对电极（13）和相应触点（14至17）的主体（11）。 工作电极（12）彼此面对地安装以在它们之间限定样本空间。 如同两个反电极（13）那样，电极（12）并联电互连。 这种布置使得可以为小体积样品空间（22）提供非常大的工作电极表面积。

摘要： This invention relates to apparatus for measuring the concentration of a volatile component in a gas and in particular, but not exclusively, to breath alcohol testing apparatus. In such apparatus (10), a pressure transducer (15) is provided to detect the ambient pressure during test. This pressure is used to modify the output of a fuel cell (11).

摘要： Testing apparatus is provided in the form of a pen and has a body (11) and cap (12). The body (11) has an inlet (13) at its tip which communicates with a fuel cell chamber (14), containing a fuel cell (15), and, via that chamber, with a passage (16) and a cylinder (17). A piston (18) is mounted in the cylinder (17) for operation by a button (19), a spring (21) and latch (22) such that it can draw air through the inlet (13) to the fuel cell (15). If the inlet (13) is placed in a user's mouth the apparatus can provide an indication of his breath alcohol concentration, for example, on display (23).

摘要： On décrit un appareil de contrôle se présentant sous la forme d'un stylo-plume et comprenant un corps (11) et un capuchon (12). Le corps (11) est pourvu d'un orifice d'entrée (13), au niveau de sa pointe, qui communique avec une chambre (14) de cellule électrochimique contenant une cellule électrochimique (15), et, à travers cette chambre, avec un passage (16) et un cylindre (17). Un piston (18) monté dans le cylindre (17) peut être actionné par un bouton (19), un ressort (21) et un élément de verrouillage (22), de sorte qu'il puisse aspirer l'air par l'orifice d'entrée (13) vers la cellule électrochimique (15). Si l'orifice d'entrée (13) est placé dans la bouche d'un utilisateur, l'appareil peut fournir une indication de la concentration d'alcool dans son haleine, par exemple, sur le dispositif d'affichage (23).
