The AEM Digital Oil Temperature Gauge combines unsurpassed accuracy, speed and control with an easy-to-read digital LED interface that displays oil temperature in 1 degree increments, and a sweeping LED "needle" that lines the edge and moves as oil temp changes from 0 to 100. The oil temperature gauge's digital readout will automatically increase and decrease in intensity due to the built in ambient light sensing photocell.AEM's digital oil 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 oil temps 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.FeaturesEasy-to-install Plug & Play harness and sensor includedGauge Readout from 100 to 300 F24 green LED display lights provide immediate reference to monitored engine functionThree digit readout in centerEach gauge comes with interchangeable black/silver bezels and black/white faceplatesAuto-dimming gauge face and read out lighting0-5v analog output included for use with data loggers and virtually any engine management systemBrass sensor included52mm (2 1/16th inch) gauge housingSpecs0-5V Analog Calibration (Linear Output)0V = 0F4.92V = 303F
