Laboratory environment detector

The invention provides a laboratory environment detector. The laboratory environment detector comprises a supporting plate; the mounting frame is fixedly mounted on the supporting plate, a detection device is fixedly mounted on one side of the mounting frame, and an air guide mechanism is mounted on the mounting frame; and the air conveying cylinder is provided with a driving mechanism, and the air conveying cylinder is connected with the driving piece through an air conveying pipe. According to the laboratory environment detector provided by the invention, through the arrangement of the treatment box, detected gas containing harmful gas can be treated and then discharged, subsequent treatment operation is avoided, the treatment efficiency is improved, the gas guide stirring mechanism can be driven to rotate through cooperation of gas flow and an impeller, and the detection efficiency is improved. The air guiding and stirring mechanism rotates while discharging air flow through the exhaust holes in the bent p
