The invention discloses a smoke sucker suction flow recording analyzer. The smoke sucker suction flow recording analyzer mainly comprises a shell, a man-machine interaction device, a gas flow detection part, an electronic circuit, an adapter and a flexible tube. The man-machine interaction device has a concise and friendly graphic user interface; the power supply of the analyzer can be switched between an external power supply and a built-in power supply; the analyzer comprises communication and external equipment interfaces to realize connection with a computer and external equipment; and the analyzer can be conveniently calibrated through a capacity detection device. The analyzer is applied in recording of the suction flow data of the smoke sucker, and has various measurement modes; and a suction flow diagram is drafted and analyzed, and the suction capacity, the suction time, the maximum suction flow and other characteristic parameters can be obtained through calculating.
