High brake system pressures make this an environment that few gauges are up to the task of handling. Auto Meter’s Digital Stepper Motor Brake Pressure Gauge provides not only the accuracy you expect from a top of the line instrument, but the durability you need under even the most demanding conditions. Includes a highly advanced 1/8” NPT Pressure Transducer and wiring harness for ease of installation. Data Logging is also possible thanks to an analog .5 - 4.5v output.
