HIGH ACCURACY Measurement range is 100-300F(38-150C),Sensor mounting thread: NPT 1/ 8 ",Power: 12V/24V DC, Max. 0.3A. SMARTER INTERFACE The Digital Gauges include new technological features that make them easier to use. Two buttons on the faceplate deliver programmability for peak/recall, standard or metric center LED readout and sweeping LED needle, and user-selectable threshold warnings. EASIER TO MOUNT Despite the larger display, Gauges are contained in a standard 2-1/16th-inch (52mm) diameter housing for mounting in a standard gauge pod. Thanks to an advanced single board design, X-Series Gauges have an incredibly slim overall depth of under 18.8mm This shallow cup depth allows Gauges to be mounted practically anywhere.
