10-2. Detection principle
[Detection principle]
An electrochemical type sensor electrolyzes a gas directly while maintaining the interface between
electrode and electrolyte at a constant potential (bias voltage). A gas is electrolyzed by an electrolysis cell
to which a certain potential (bias voltage) is applied, and the gas is detected from the electrolytic current
generated at that time.
