Description

Technical Field

[0001] The utility model relates to the technical field of gas detection, in particular to a cabinet-type gas sampling and analysis device. Background Art

[0002] In the field of gas sampling and analysis technology, with the development of industry, the improvement of environmental protection awareness and the growth of scientific research needs, the requirements for gas sampling and analysis devices are also increasing. However, traditional gas sampling and analysis devices usually need to go through multiple independent filtration and dehumidification steps before the gas enters the analysis system. These steps often involve multiple devices and components, resulting in a complex structure of the entire device and a large space occupation. At the same time, due to the dispersion of the filtration and dehumidification mechanisms, it is not conducive to the subsequent material replacement and cleaning, which increases maintenance costs and time. Therefore, we propose a cabinet-type gas sampling and analysis device to solve the above problems. Utility Model Content
