This gas detector applies an electrochemical sensor. The sample gas is electrolyzed by the
electrolyzed cell added with specific electric potential (bias voltage) and detected from the
electrolyzed current generated at that time.
The electrochemical sensor is designed to keep the interface between electrode and electrolyte
at a constant potential (Bias voltage) and is the method to electrolyze gas directly. Then as the
gas has the bias voltage generating its own electrolization (Redox reaction) the bias voltage of
sensor is determined by the redox potential.
