Nitrogen oxides have adverse effects on human health and the environment, such as causing respiratory diseases, acid rain, greenhouse effect, etc. In order to control the emission of nitrogen oxides, it is generally necessary to install a nitrogen oxide measuring gun in the exhaust system of the combustion equipment to monitor and adjust the concentration of nitrogen oxides.

[0003] The nitrogen oxide measuring gun is an instrument that uses ultraviolet absorption or chemiluminescence to measure nitrogen oxides. Its working principle is to react nitrogen oxides in exhaust gas with specific reagents to generate ultraviolet light or visible light, and then measure the light intensity through a photoelectric detector to calculate the concentration of nitrogen oxides. The nitrogen oxide measuring gun is generally composed of a gun body, a gun head, a probe, a cable and other parts. The gun head is the core component of the nitrogen oxide measuring gun, which is responsible for introducing the exhaust gas into the probe and reacting with the reagent.
