A controllable-airflow-source standard appliance testing measuring device comprises a straight line suction system, a measurement testing system and a control system used for controlling the suction system and the measurement testing system, and is characterized in that the measurement testing system comprises a constant pressure flow measuring unit used for testing standard appliances of cigarette standard rods and ventilation rate standard rods, and a constant flow pressure measuring unit used for testing the cigarette paper air permeability standard appliance; the two units are connected in parallel, and are mounted at a working interface at the air outlet at the front end of a piston cylinder body in the straight line suction system, and the testing mode conversion of the two units are controlled through a mode change-over switch arranged in the control system. The device has the prominent advantages that the integration of functions of constant flow pressure measuring and constant pressure flow measuring is realized, that is, testing and measuring of the air permeability standard appliance, the cigarette resistance suction standard rods and ventilation rate can be realized on the same instrument.
