The digital air pressure gauge includes an error correction lookup table database stored within a memory device within the gauge. The database includes reference air pressure values and associated measured air pressure values, where the reference air pressure values and associated measured air pressure values are determined at identical discrete time intervals as pressurized air is input into the gauge. A transducer generates an electrical signal representative of air pressure within a device such as a pneumatic tire. A microprocessor compares the electrical signal with measured air pressure values within the database and determines a closest measured air pressure value. The microprocessor then determines the associated reference air pressure value of the closest measured air pressure value. The reference air pressure value is then displayed as the accurate pressure of the pressurized air within the device. The gauge may be disposed within a tire valve cap with an RF transmitter.
