[0002] An oxygen sensor is a device used to detect the oxygen concentration in the environment, usually called an oxygen gas sensor or an oxygen concentration sensor. An oxygen sensor generally consists of an oxygen ion electrolyte layer, a reference electrode, and a working electrode. The oxygen ion electrolyte layer is located between the two electrodes and surrounds the reference electrode. When oxygen passes through the sensor, it reacts with the electrolyte, resulting in a potential difference between the reference electrode and the working electrode. Oxygen sensors usually need to work in a high-temperature environment to promote the movement of oxygen ions in the electrolyte. During the production process of oxygen sensors, it is necessary to detect the performance of oxygen sensors. However, in the prior art, when using the detection device for oxygen sensors, it is usually not convenient to quickly adjust the oxygen concentration and the detection ambient temperature, and it is difficult to quickly move the oxygen sensor to the temperature control area for detection, which needs to be further improved.
