3in1 Digital Air Pressure Gauge
Comes with harness and pressure sensors (1/8")
Digital pressure gauges are used to read the pressure in your system's bags or reservoir.
Unlike analog pressure gauges, you need to pass an air hose through the car for each pressure reading, with digital ones you only need to pass the electrical harness. Digital gauges can be more expensive than most analog gauges but considerably easier to see and install.
