度測定器。[Claims for Utility Model Registration] (1) It consists of a main body case, a sensor probe, and a tube that connects them. There are two tube connections that lead to the internal pressure measuring section and the flow rate measuring section, respectively, and on the surface of the case there is an indicator that indicates the pressure inside the probe, a digital indicator that numerically indicates the flow rate, and a pressure measuring section. A pressure adjustment knob is provided inside the case, and means for applying a constant suction or discharge force into the probe, and means for measuring the pressure and flow rate within the probe, respectively, are provided at the tip of the probe. A cap with a hole with an internal area of 1 cm 2 is attached, and two tubes are connected to the rear end, forming a sealed structure that prevents air from leaking from any part other than the tube and the hole in the cap. A portable air permeability measuring device in which the other ends of the tubes are each connected to the tube connection portions on the sides of the main body case. (2) The internal area of the tip of the probe is a multiple of 1 cm 2 , and an operator is provided to divide the flow rate value that is measured by contacting the fabric sample and output by the internal area, so that it is output to the digital indicator. The portable air permeability measuring device according to claim 1, characterized in that:
