Abstract: PURPOSE: A device for testing the threshold gas pressure and the gas permeability of a porous medium is provided to install a nozzle unit in which gas is injected and discharged in a form of radial grooves or a porous plates so that the gas is evenly in contact with a specimen. CONSTITUTION: A device for testing the threshold gas pressure and the gas permeability of a porous medium includes a pressure container body (100), nozzle units (110), a rubber sleeve (120), a second injection connection unit (150), a second discharge connection unit (151), and a cover (140). The nozzle units are arranged inside the body and include a first injection connection unit (111) injecting gas in order to move the gas; and a first discharge connection unit (112). The nozzle units in which sleeves (160) of a Teflon material are joined are placed in the upstream and the lower stream of a specimen (170). The nozzle units include radial grooves on the faces in contact with the specimen. The rubber sleeve is arranged inside the body to surround the nozzle unit and the outer periphery of the specimen and applies pressure to the specimen by using the pressure of fluid sent to an external space. The fluid flows into a space between the body and the rubber sleeve from the outside of the body via the second injection connection unit and the second discharge connection unit.
