Model 1 Auto Ranging Digital

The Model 1 auto-ranging technology uses multiple piezoresistive sensors to read the entire range using just one gauge where it would otherwise require up to seven of our closest competitors digital gauges. It measures from absolute zero to 3000 psi and absolute without changing ports or pressing buttons. The new Winchester has full noise immunity, timer for backlight, cal date, serial number and battery voltage. It’s rugged, shockproof design comes equipped with a protective rubber housing.
