A digital measuring device includes a housing, at least one measuring head, at least one measuring sensor, at least one digital measurement circuit, and at least one power supply unit. The measuring head is arranged outside the housing. The measuring head functions to carry out an operation of tightening a tire valve core, connecting a valve stem, or measuring tire tread. The measuring sensor is arranged inside the housing and coupled to the measuring head to measure and detect a detection signal indicating an output of a tire valve core tightening torque, a tire pressure, or a tire tread depth. The digital measurement circuit is connected to the measuring sensor for computing, displaying, and issuing an alarm regarding the tightening torque that the measuring head applies to tighten a tire valve core, the tire pressure, or the tire tread depth. The power supply unit supplies a desired direct-current working power to the measuring sensor and the digital measurement circuit. As such, a device that is capable of digital measurement, displaying, and issuing an alarm regarding the tire valve core tightening torque, the tire pressure, or the tire tread depth is formed. |
