DHAVI Combined Gas Analyzer (EPM-1602), the Combined gas analyzer is used to measure the concentration of gases in the air. The device consists of two parts: an electrochemical cell and a microprocessor-based data acquisition system. In the electrochemical cell, the sample gas is oxidized or reduced depending on its chemical composition. The resulting current is measured using a potentiostat circuit. The output signal is converted into digital format and processed by the microprocessor-based data acquisition unit. The software package includes a graphical user interface that allows the operator to set up the instrument and start the measurement process
