Motion Pro Digital Tire Pressure Gauge Here you have it. The Motion Pro Digital Tire Pressure Gauge is the gauge against which all other tire pressure gauges are...gauged. Motion Pro's well-earned reputation is built on a tough billet aluminum body and chuck for durability, an oversized display that features a cool blue back light and a dual-swivel chuck that is engineered in-house. When it comes to precision, the Motion Pro Tire Gauge also packs class-leading accuracy. The Motion Pro Digital Pressure Gauge provides tire pressure readouts in 0.1 PSI increments with a tested accuracy of 0.6 Psi. Pressure readouts are continuous when airing down via bleed valve - no need to reset. The unit has four selectable scales: Psi, Bar, Kg-Cm2 and kPa. Even the AAA batteries are included.
