[0002] Pneumatic instruments are devices that measure, control and adjust parameters such as gas flow, pressure and temperature. They are used in many industrial fields. Pneumatic instruments can be used for environmental testing, especially for the detection of gas parameters. For example, pressure sensors can be used to monitor the pressure of gas in pipelines, flow meters can be used to measure the flow of gas such as fuel gas and air, and thermometers can be used to detect ambient temperature. These instruments can help us understand the concentration or parameter changes of various gases in the environment at different times and locations, so as to better monitor and manage the environment. Pneumatic instruments have important application value in environmental testing.

[0003] The pneumatic instruments currently on the market still have the following shortcomings: 1. The existing pneumatic instruments can only detect the current position when detecting through sensors, and cannot make the device detect gas parameters at different heights; 2. The existing pneumatic instruments are installed at high places through poles when in use. When the sensor of the pneumatic instrument fails, it is not convenient for personnel to quickly remove it for maintenance, which increases the working time. Utility Model Content
