Abstract
A digital pressure gauge comprises a power supply, an input button unit, a pressure sensor, a display unit, a warning unit, and a control unit. The control unit counts the number of operations and/or operation duration of the digital pressure gauge and generates an alarm through the display unit and the warning unit when the counted number of operations and/or operation duration of the digital pressure gauge exceeds a threshold.
