ABSTRACT:
Disclosed is a pressure gauge including a body forming an inlet, an outlet, and a shunt hole. A pressure meter is provided to the shunt hole. An inlet duct in connection with an inflation device is provided to the inlet. A check valve is arranged in the inlet duct. An outlet duct is connected to the outlet and is prepared with an inflation mouth for coupling with an intake nozzle of an object to be inflated. When an inflation device is operated to charge air into an object for inflation through the inlet duct, the body, and the outlet duct, a pressure measuring process can be performed concurrently.
