This ARB Digital Tire Inflator features a blue backlit digital LCD display with battery indicator and displays measurements in units from 0-200 PSI, 0-14 Bar or 0-1400 Kpa. It features rubberized housing so you dont have to worry about dropping it or shock loads. The 23-1/2" braided hose with clip on chuck makes it easy to use so you don't have to stay bent down. 1 PSI margin of error means you'll always have accurate readings. 2 AAA batteries, included, power the unit while it still features auto on/off for increased battery life.
