Principle Description

Electrochemical gas analyzer is a chemical gas analysis instrument. It measures gas composition based on changes in ion concentration or current caused by chemical reactions. In order to improve selectivity, prevent surface contamination of measuring electrodes, and maintain electrolyte performance, a diaphragm structure is generally used. The commonly used electrochemical analyzers include positioning electrolysis and galvanic cell.
