Show original supplier description
It boasts a range of 100-300°F (40-150°C) with a clear, high-visibility digital LED display that is 87% larger than previous AEM digital gauges, complemented by a sweeping green LED needle for quick reference. Installation is made easier by its standard 2-1/16th-inch (52mm) diameter housing, compatible with most gauge pods. The gauge's advanced single-board design results in an exceptionally slim profile, with an overall depth under 0.825 inches and a cup depth of only 0.200 inches, enabling mounting in tight spaces. Advanced features include a user-programmable interface with two buttons on the faceplate for peak/recall functions, selecting between standard (Fahrenheit) or metric (Celsius) center LED readouts, and setting user-selectable threshold warnings. The gauge is AEMnet CAN-bus enabled, allowing for daisy-chaining with other AEM devices or compatible EMS/loggers, and also provides 0-5V analog outputs for data logging. This gauge comes standard with a black bezel and black water temperature faceplate. Optional accessory kits are available separately to provide a silver bezel and white faceplates for water, transmission, and oil temperature, each featuring dual-sided Fahrenheit and Celsius calibration.
