Abstract
A portable tire pressure gauge measures a value of tire pressure. The gauge can display the measured value digitally and selectively in one of different units of pressure. If the gauge is made for use in a country, the gauge can output the measured value aurally and selectively in one of two languages that a majority of people in the country understand. These languages may be the language of the country and a first foreign language in the country. The gauge includes a display, a switch, a solar battery and an audio output unit. The display digitally displays the measured value. The switch switches the different units of pressure. The solar battery is the power supply for measurement and display. The audio output unit can output the measured value aurally and selectively in one of the two languages.
