FSS-A80型电化学酒精传感器是一种电化学库仑分析池型酒精浓度检测器件，专门用于呼气中酒精浓度检测。

它的基本特征是：更好的准确性、极好的稳定性、极高灵敏度和较快的响应速度、较好的抗湿性能、对口气没有响应。

FSS-A80型电化学酒精传感的工作电流不到一个微安，功耗极低。

FSS-A80型电化学酒精传感器适宜于呼气中酒精浓度的检测，用于警用酒精检测装置、汽车点火控制系统等。

FSS-A80 alcohol sensor is a electrochemical Coulometry cell which is designed for breath alcohol detection. It gives high sensitivity and accuracy to alcohol vapors with quickly response rate at high relative humidity. It is a low power consumption device and has no response to bad breath. FSS-A80 is more suitable for breath detection and automobile ignition locking systems.
结构（Structure）
FSS-A80型电化学酒精传感器的关键部件是一个由担载了特制的催化剂的工作电极，在一定的工作电位下，催化剂将空气中的酒精蒸汽氧化，氧化电流与酒精的浓度直接相关。

The most special component of FSS-A80 is the working electrode with a special catalyst coat. The alcohol vapor oxidized on the surface of the catalyst and the oxidization current is related to the concentration of alcohol vapor directly.
