3 in 1 LCD Gauge for Water Temp, Oil Pressure and Voltage (12V/24V)

Meet the 3 in 1 LCD Gauge from SDAO—a compact, digital dashboard solution that shows water temperature, oil pressure, and battery/altimeter voltage in one clear display. Sized at 55 mm by 99 mm by 14 mm with a plastic shell, it fits snugly in car or motorcycle dashboards and is equally ready for custom builds. It operates from DC 9V–36V and provides fast, stable readings in just a few seconds, helping you catch issues before they become costly. The sensor suite includes a temperature sensor with M10 threading and an oil pressure sensor with 1/8 NPT, plus a ready-to-wire cable set for straightforward installation. All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty. At intercyprus.com since 2002 — trusted for quality and reliability. The unit also features a voltage alarm that flashes when the monitored voltage falls below 10V, sits between 16–20V, or rises above 31V, so you can react quickly to electrical system changes.

Benefits & Tips

• Consolidates three critical readings—water temperature, oil pressure, and voltage—into a single, easy‑to‑read display, reducing mystery gauges on your dash.
• Ideal for cars, motorcycles, or custom builds where space is limited and reliable sensor data matters for maintenance and performance.
• Use the voltage alarm to safeguard your electrical system: monitor battery health and alternator output, and get a visual alert if voltages stray from safe ranges.
