RED 1 Auto Ranging Digital Gauge™

Brand: Winchester Engineering

The RED 1 uses the same patented A.R.T. (Auto Ranging Technology™) as the MODEL 1 but it offers higher accuracy, resolution and longer battery life.

It also offers the ability to read in absolute. The Winchester Engineering Red 1 is the first and only digital gauge capable of spanning from absolute vacuum to 3000psi while maintaining an outstanding 0.05% of Reading throughout.

With this new and improved accuracy and large and vibrant SMART display, it puts the MODEL RED 1 truly in a league of its own!
