The mixing ball 21 with a hollow interior can be used to mix industrial waste gases from different directions to ensure the accuracy and uniformity of sulfur dioxide detection. The combination of the air intake branch pipe 40 and the connecting screw hole 22 allows the mixing ball 21 to be connected to multiple gas collecting hoods 44, so that industrial waste gases at multiple locations can be detected at the same time, thereby reducing errors and improving the accuracy of detection. Through the design of the gas collecting hood 44, waste gases can be collected in a directional manner to improve the collection efficiency of waste gases, while preventing waste gas diffusion and protecting the surrounding environment.

[0031] Furthermore, a gas data display screen 11 is installed on the outer wall of the detection host 10, which can display the detected sulfur dioxide concentration data in real time, so that the operator can quickly and intuitively understand the sulfur dioxide level in the current industrial waste gas, and make corresponding adjustments or take necessary measures.
