PROBLEM TO BE SOLVED: To provide an air flow tracking device for measuring combustion propagation analysis between fuel droplets and flame spreading in the nongravitaional or microgravitational state by PTV measurement, and a test method of a flame propagation mode by the PTV measurement between fuel droplet particles. SOLUTION: This measuring device for combustion propagation analysis and flame spreading has (a) in a housing or in a partitioned space, (b) a suspension line support base for supporting a suspension line, (c) a droplet generation device for generating a simulated droplet, (d) a tracer particle supply device for supplying a tracer particle cloud, and (e) an ignition device, and also has (f) an optical measuring system and (g) a sequencer for controlling them. In the device, (d) the tracer particle supply device has (d1) a tracer particle selection means for removing gross particles in the tracer particles and supplying only particles having the uniform particle size.
