Promotional products: Our new digital tire gauge quickly measures your tire pressure in either PSI, Bar, KPa, or kgf/cm2 with a range of .5-99.5 PSI. The pressure is displayed on the LCD and conveniently "speaks" the tire pressure reading when you press the button on the top of the unit. Perfect for pressure readings in low light situations. Gauge resets when each measurement is taken and remembers the last reading. Features auto shut-off to conserve battery life. Operates on two button cell batteries included.
