The Accutire MS-4021B digital tire pressure gauge features a large, easy to read LCD display that provides pressure readings from 5-150 PSI in 0.5-pound increments. It is ergonomically designed with an angled head and a rubber coated easy-grip handle. The heavy-duty construction will easily withstand shifting around in your glove compartment or toolbox. If you forget to turn the gauge off, don't worry, it is equipped with an automatic shut off system. What's more, the included lithium battery will never need to be recharged or replaced.
