PROBLEM TO BE SOLVED: To provide a digital pressure gauge in which a self-control feature and an adjustment history management feature are imparted to have pressure characteristics suited for a standard owned by a user as well as to reduce adjustment costs and prevent quality deterioration. SOLUTION: The digital pressure gauge to measure pressure based on output signals of a pressure sensor and a preset correction factor comprises a correction factor calculation means which calculates the correction factor based on output signals when predetermined standard pressure is applied to the pressure sensor and stores the correction factor into a storage means, and a history creation means which creates history information on the correction factor and stores the information into the storage means.
