电化学传感器的构成是:将两个反应电极――工作电极和对电极以及一个参比电极放置在特定电解液中,然后在反应电极之间加上足够的电压,使透过涂有重金属催化剂薄膜的待测气体进行氧化还原反应,再通过仪器中的电路系统测量气体电解时产生的电流,然后由其中的微处理器计算出气体的浓度.电化学传感器结构示意图与工作原理图如下图所示.气体首先通过微小的毛管型开孔与传感器发生反应,然后是憎水屏障,最终到达电极表面.穿过屏障扩散的气体与传感电极发生反应,传感电极可以采用氧化机理或还原机理.这些反应由针对目标气体而设计的电极材料进行催化.通过电极间连接的电阻器,与电气浓度成正比的电流会在正极与负极间流动.测量该电流即可确定气体浓度.

The electrochemical sensor is:will constitute two reactions - work of electrode and electrode electrode and a reference electrodes placed in particular electrolyte,and then in the reaction between electrode voltages,add enough metal catalysts are through the film for measuring gas REDOX reaction,then the circuit by electrolysis gas produced when measuring system,then the current by microprocessor calculate gas concentrations.Electrochemical sensor structure and working principle chart drawing shown below.The first through tiny gas hole and capillary type sensor,and then is disgusting,water barrier to the electrode surface.Through the barrier of gas sensor electrode and diffusion,sensor electrode can react by oxidation mechanism or reduction mechanism.These reactions by targeting gas and design of catalytic electrode materials.The connections between the electrodes,and electrical concentration resistor is proportional to the current will flow in the positive and negative.Measure the concentration of gas current can be determined.
