Milton Digital: Made with a LCD screen measuring in increments of 0.1 PSI and backlit for better measurement reading in dark environments. Our digital gauges also come with a 360 degree swivel gauge (head rotates for an easy and comfortable measurement reading) and +/- 1 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-absorbing 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.
Milton Analog: No need to worry about batteries with this analog inflator gauge, oil-filled to provide optimal accuracy, pressure spike prevention, and a cushioned tick to optimize the lifespan of mechanical parts inside the gauge. This also has a deflate button for if you overshoot the pressure. The dial gauge is fitted with a rubber boot which protects it from corrosion, impacts, and shocks. 2 units of measurement: PSI and Bar.
WHY LIQUID-FILLED? Pros know that liquid absorbs vibration and pressure spikes, lubricates and reduces wear of moving parts, protects against moisture penetration and icing, and is better in corrosive environments.
