The utility model relates to an air monitor with an electrochemical sensor self-detection system. The air monitor with the electrochemical sensor self-detection system comprises an air monitor shell,an electrochemical sensor, a sensor and a controller, wherein an accommodating cavity is formed in the air monitor shell; the heat insulation plate is arranged in the air monitor shell and divides thecontaining cavity into a first cavity body and a second cavity body; the electrochemical sensor is arranged in the second cavity; and the self-detection system comprises a standard gas output end. According to the air monitor with the electrochemical sensor self-detection system, standard mixed gas of the self-detection system is injected into the second cavity; whether the electrochemical sensoris inaccurate or not can be judged through a method for detecting the components of the standard mixed gas by the electrochemical sensor, so that whether the electrochemical sensor is replaced or maintained or not is considere
