Description

technical field [0001] The invention relates to the technical field of electrochemical sensors, in particular to an electrochemical sensor testing system and testing method. Background technique [0002] Electrochemical sensors are part of the sensor application field, mainly used to detect poisonous and harmful gases, and are widely used in petrochemical and other dangerous places where toxic and harmful gases are easily produced. The signal processing system of the electrochemical sensor includes a constant voltage control circuit and a current-voltage conversion circuit. According to the signal processing principle of the electrochemical sensor, it can be known that in the actual application process, no current flows through the electrochemical sensor, and the signal processing output voltage of the electrochemical sensor is a fixed voltage. However, there are many situations that cause no current in the electrochemical sensor, such as: 1) the electrochemical sensor is i...
