Abstract

The present application discloses a calibration and detection device for a nitrogen-oxygen sensor, which includes a main engine, on which an exhaust module for discharging exhaust gas and a detection module for receiving a detection signal of a probe and displaying a numerical value of nitrogen oxide content are arranged. The exhaust module is electrically connected with the detection module, and the present application has the effect of being able to detect the inductive performance of the probe.

Description

technical field [0001] The present application relates to the technical field of nitrogen and oxygen sensors, in particular to a calibration and detection device for nitrogen and oxygen sensors. Background technique [0002] Nitrogen oxides are one of the main factors that form photochemical smog and acid rain, which will pollute the environment and seriously endanger human health. The main source of nitrogen oxides in the urban atmosphere is fuel combustion, such as vehicle exhaust emissions, so nitrogen oxide sensors are often used to detect nitrogen oxides in vehicle exhaust. [0003] In related technologies, such as figure 1 A nitrogen and oxygen sensor is disclosed as shown, which includes a cable 1, a probe 2 connected to one end of the cable 1, a plug 3 connected to the other end of the cable 1, and a control circuit board 4 connected to the plug 3. The control circuit board 4 The socket is provided with a socket for plugging and mating with the plug 3, so as to rea...
