    AEM Electronics 30-4402 Details

    The AEM Digital Water Temperature Gauge combines unsurpassed accuracy, speed and control with an easy-to-read digital LED interface that displays water temperature in 1-degree increments, and a sweeping LED "needle" that lines the edge and moves as water temperature changes from 0 to 300. The water temperature gauge's digital readout will automatically increase and decrease in intensity due to the built-in ambient light sensing photocell.

    AEM's digital water temp gauge includes a 0-5v analog output for use with data loggers and virtually any engine management system, such as the Infinity ECU, Series 2 EMS or AQ-1 Data Logger, making it the perfect solution for users who need to monitor and data log water temp at high RPM on tuned engines. Each gauge includes interchangeable silver and black bezels and black and white faceplates to personalize the look of your gauge.
