Abstract
(EN)
The present invention relates to an electrochemical gas sensor, and more particularly, to an electrochemical gas sensor having a double action electrode. One embodiment of the electrochemical gas sensor having a double electrode structure, according to the present invention, comprises: a housing in which a first gas inlet and a second gas inlet are formed; a first sensing electrode disposed below the first gas inlet in the housing and reacting with the gas introduced through the first gas inlet; a second sensing electrode disposed below the second gas inlet in the housing and reacting with gas introduced through the second gas inlet; a detection gas removing filter disposed between the second gas inlet and the second sensing electrode, and filtering the inflow of sensing gas to be sensed into the second sensing electrode; a reference electrode disposed below the first sensing electrode and the second sensing electrode; and a counter electrode disposed below the reference electrode.
