The Milton Industries 900 Series Field Re-Calibratable Service Gage provides patent-pending “Quick Click” accuracy. This means, with each click of the calibration the tool adjusts the psi by +/- 0.25. The Field Re-Calibratable Gage has a range of 10 to 160 psi. It features a corrosion-resistant chrome-plated brass tubular body and a premium black anodized aluminum indicator bar. An extended-reach chuck and off-set head make it easier to measure tire pressure at almost any angle. A simple hanging hook allows for easy access wall storage. The 900 series is a rugged, handy tool for a home garage or busy automotive repair or tire shop.
