Product Overview
The SINCO TECH OBDII Water Temperature Gauge is engineered for modern drivers who demand precise engine monitoring without the hassle of complex installations. Designed to fit seamlessly into any 12‑volt vehicle equipped with a standard OBDII port, this gauge reads coolant temperature, engine RPM, and battery voltage in real time. Its compact housing measures 9.84 x 4.72 x 3.54 inches and weighs just 1.1 pounds, making it an unobtrusive addition to any dashboard. The device supports vehicles from 2002 onward, ensuring broad compatibility across cars, trucks, and SUVs. A selectable seven‑color backlight—white, red, green, yellow, purple, blue, and pale blue—provides optimal visibility under any lighting condition, from bright daylight to night‑time driving.
