Long-optical-path corrosion-resistant gas absorption cell

The utility model belongs to the technical field of waste gas monitoring equipment, and provides a long-optical-path corrosion-resistant gas absorption cell which comprises an absorption cell body, a Teflon tube is arranged on the inner side of the absorption cell body, a lens mechanism and a reflector mechanism are arranged at the two ends of the absorption cell body respectively, and the lens mechanism and the reflector mechanism are arranged on the inner side of the absorption cell body. The lens mechanism is connected with an optical fiber interface, and the lens mechanism and the reflector mechanism are both connected with gas circuit interfaces communicated with the Teflon pipe. According to the utility model, the separation of a light path and a gas path is realized, and the problems of inconvenience in maintenance, low measurement precision and high processing cost of the existing gas absorption cell are solved. 本实用新型属于废气监测设备技术领域，提供了一种长光程耐腐蚀气体吸收池，所述长光程耐腐蚀气体吸收池包括吸收池本体，所述吸收池本体内侧设有特氟龙管，所述吸收池本体两端分别设置有透镜机构
