PURPOSE: A measuring device is provided to measure a volume and pressure simultaneously without a separate volume measuring device or a separate pressure measuring device, thereby reducing expenses. CONSTITUTION: A measuring device comprises a reaction unit(112), a volume measurement container(134), and a pressure measuring unit(136). A receiving unit is arranged in the inner central portion of the reaction unit body. The reaction unit includes a left screw hole, a right screw hole, and a first vertical hole, and a second vertical hole. The volume measuring container receives liquid and gas discharged through the right screw hole and measures the volume of the liquid and the gas. The pressure measuring unit measures the pressure of the gas when the liquid and the gas are received in the volume measuring container.
