The MEASUREMAN Dual Needle Air Gauge with Paddle Switch is designed for convenient in-cab air pressure control in air suspension systems. Featuring two separate electric paddle switches, it allows independent inflation and deflation of left and right air springs for more accurate leveling and control. The 200 PSI dual needle gauge provides clear pressure readings, while the LED backlight improves visibility in low-light conditions. Built with a 1/8" NPT rear mount and designed for 1/4 inch air hose connection, it offers easy installation and reliable operation. Compatible with both 12V and 24V systems, this gauge is ideal for air suspension kits, air ride systems, and other onboard air pressure control applications, helping maintain proper rear leveling when towing or hauling heavy loads for a smoother and more stable ride.
