What are the differences between instrument equipment for high altitudes and that for areas below 1,000 meters, and what are the requirements for selecting such equipment? Especially, how should it be done in terms of debugging?
No matter how high the altitude, it still operates under certain pressure and temperature conditions; therefore, in my opinion, apart from paying attention to the minimum ambient temperature, it is sufficient to ensure proper heat tracing and insulation； Also, pay attention to the range of the instruments, especially the range for liquid levels; as for why, you’ll have to figure it out on your own.
In fact, the main consideration should be the accuracy of value transfer. Different altitudes result in different values of gravitational acceleration, and this has little to do with the selection of instruments; the key lies in the calibration process, especially regarding the reference for the pressure zero point, such as the weights used in piston manometers.

I’m thinking that different altitudes must affect pressure measurements, as atmospheric pressure varies greatly. For example, the natural conditions in our factory area are as follows: Altitude: 1800 m; Seismic intensity: 9 degrees; Atmospheric pressure: 81.57 kPa; Air density: 0.95 kg/m3
