Zusammenfassung:	Embodiments of the present application disclose an apparatus for detecting air tightness. The apparatus has an air inlet end, an inflating end for an object to be tested inflating end and a standard part inflating end. The apparatus includes a pressure regulating component, a first bypass isolating valve, a second bypass isolating valve, a third bypass isolating valve, a first high air pressure sensor, a second high air pressure sensor, a low air pressure sensor, and a differential pressure sensor. By adopting the technical solutions according to the embodiments of the present application, a low air pressure sensor can be embedded in an air tightness detector suitable for tests under high pressure and the low air pressure sensor can be effectively protected in a high pressure environment, so that leakage tests under different inflation pressures can be implemented by one instrument.
