OLED (Organic LED) Temperature Meter is designed to withstand constant vibration and the rigors of a wet marine or dusty outback environment. Includes a prewired temperature sensor with a 6’ cable. Monitors temperature on a bright, waterproof, daylight readable OLED screen. High contrast and resolution make this screen visible from a wide viewing angle, even with polarized sunglasses. Reverse polarity protected. Same compact round size as a standard 12V receptacle, this OLED Temperature Meter supports many installation options. Constructed of injection molded nylon. Installation is as easy as drilling a 1-1/8" hole, inserting the socket body, tightening the locking nut, and connecting the wires.
