電氣化學(xué)組件通常用于測量有毒和無毒氣體，例如：一氧化碳、氧氣和氫氣。它們基于化學(xué)氧化與化學(xué)還原的主要方法，并產(chǎn)生與被測氣體成比例的電流。大多數(shù)組件均由三個電極組成：工作極(WE)、計數(shù)器極(CE)和基準(zhǔn)極(RE)。WE氧化或者還原目標(biāo)氣體，然后產(chǎn)生一個與氣體濃度成比例關(guān)系的電流。CE平衡所產(chǎn)生的電流，而RE則維持工作電極電位以保證正確的工作區(qū)。電氣化學(xué)組件往往連接恒電位器電路。這種恒電位器電路向CE提供電流(并在要求時偏置)。它讓W(xué)E保持與RE相同的電位，并使用一個跨阻抗放大器(TIA)把WE的輸出電流轉(zhuǎn)換為電壓。

與許多傳感器一樣，電氣化學(xué)傳感器具有對溫度的依賴性。為了實現(xiàn)較佳性能，需測量這種組件的溫度。根據(jù)組件的性能與溫度的對比曲線圖(參見數(shù)據(jù)表)，進行正確的溫度校正。
