Description

Technical Field

[0001] The utility model relates to the technical field of gas analysis instruments, in particular to a damage prevention structure of a gas analysis instrument. Background Art

[0002] Gas analyzers are often used in the production process of chemical reactions. Due to the great differences in the gases being analyzed and the variety of analysis principles, there are many types of gas analyzers, including thermal conductivity gas analyzers, electrochemical gas analyzers, and infrared absorption analyzers. Among them, existing infrared online gas analyzers are placed naked when in use. A control panel and a display are provided on the outside of the shell of the infrared online gas analyzer. The infrared online gas analyzer is easy to slip out of the hands of the staff during use. The impact between the infrared online gas analyzer and the ground when it falls can easily cause damage to the display and the operation panel, affecting the staff's normal use of it.
