Gas absorption device

The utility model discloses a gas absorption device. The gas absorption device comprises an absorption cell assembly; the conversion assembly is connected with the absorption cell assembly; the control module is connected with the absorption cell assembly; the connecting assembly is connected with the conversion assembly and the absorption cell assembly; the heating assembly is arranged on the outer side of the absorption cell assembly. The gas absorption device provided by the utility model can uniformly heat the absorption cell assembly, so that a high-temperature environment is kept in the absorption cell, gas in the absorption cell can be prevented from being condensed or adsorbed on the inner wall of the absorption cell, the gas concentration uniformity is ensured, the gas concentration measurement accuracy of the device can be improved, and the gas absorption efficiency is improved. Meanwhile, the types of gas absorption and analysis can be increased, and the application range of the device is expanded.
