MiltonÂŽ PRO Series Digital Pistol Grip Inflator Gauge - Classic Dual Head Chuck, 1" Hose Optimize your tire pressure accuracy with this digital inflator gauge, made with a LCD screen measuring in increments of 0.1 PSI and back-lit for better measurement reading in dark environments. This comes with a 15 inch hose and a Dual Head Chuck, for greater accessibility with less hassle. Our digital gauges also come with a 360 degree swivel gauge (head rotates for an easy and comfortable measurement reading) and +/- 0.5 PSI accuracy across a range of 0-255 PSI. This turns on automatically when it detects pressure and includes an Auto-shut off feature after 15 seconds that saves on battery life. Designed with a rugged and ergonomic handle grip, shock-resistant rubber boot, and deflate button for overshot tire pressure. This provides 4 units of measurements: (PSI, Bar, kg/cm2, kPa), compared to the traditional 2 units from an analog gauge. Carbon fiber gauge face appearance with a protective rubber boot to shield against impacts. Comfort molded nylon handle with coating is incredibly durable and ergonomic. Steel inflator trigger with separate brass deflation button for quick fine tuning in case you go past your target pressure. Solid brass fittings throughout provide long-lasting performance, with 1/4" NPT female air inlet (MiltonÂŽ 727 plug is recommended).

Warranty: 1 year INSTRUCTIONS FOR USE: If using a dual head type tire chuck with an inflator gauge and notice air is escaping through the off-side once connected to the tireâ??s Schrader valve, simply release the trigger and remove the inflator from the Schrader/tire valve. Point the straight side of the outlet up into the air (make sure itâ??s not pointed at someone). Squeeze trigger, allow air to flow (gravity will cause the sealing valve to drop), and place the chuck end onto the Schrader/tire valve while air is still flowing. Air will start to flow into the tire. Dual head type tire chucks are unable to inflate a completely flat (zero air pressure) tire. Tire air pressure would normally cause the sealing valve to move and seal the unused side of the chuck. However, if a tire has 0 air pressure, the self-sealing valve has no pressure to reac
