3 in 1 Car LCD Digital Gauge | Voltmeter Oil Pressure Water Temp 12-24V

Key Features

• 3-in-1 Digital Display — It shows voltage, oil pressure, and water temperature in one digital unit for a cleaner dashboard setup.
• Wide 9V–36V Range — The power range is 9V–36V DC, which covers 12V and 24V electrical systems.
• Anti-Vibration Construction — Anti-vibration and anti-bump construction keeps the gauge steady on rough roads or off-road terrain.
• Quick 3–5 Second Readings — Readings update in 3–5 seconds, so you see changes soon after starting the engine.
• Low Power Draw — Its low power consumption puts minimal strain on the vehicle battery over long periods of use.

What It Is / How It Works

This 3-in-1 car LCD digital gauge combines a voltmeter, an oil pressure gauge, and a water temperature gauge into one compact unit. It is designed for 12-24V vehicles and gives real-time readings on a digital display.

Who It's For / Use Cases

Car owners who want to track engine health without fitting several separate gauges will find this useful. Truck drivers who need readings for voltage, oil pressure, and coolant temperature on long hauls are another good fit. Motorcycle riders who want a compact, weather-resistant gauge to monitor engine vitals on the go can use it as well.

How to Use / Care

1. Connect the gauge to a DC electrical system within the 9V–36V range, which covers 12V and 24V vehicles.
2. Install the oil pressure sensor into an available 1/8 NPT port on the engine block, or use an adapter if needed.
3. Read voltage at startup, oil pressure on steep climbs, and water temperature on long summer drives.
4. Allow 3–5 seconds for each measurement to update after you start the engine or notice a change.

How to Choose

Start by confirming your vehicle runs a 12V or 24V electrical system, since the power range is 9V–36V DC. Check the thread at each mounting point: the oil pressure sensor uses 1/8 NPT and the temperature sensor uses M10. Compare the 55mm x 99mm x 14mm size with the open space on your dashboard or console before you decide.

Frequently Asked Questions

Will this gauge work on a 12V car?
Yes, it works on both 12V and 24V systems, including most cars, trucks, and motorcycles.

Can I use this gauge on a motorcycle?
Yes, it is suitable for motorcycles as long as the electrical system stays within the 9V–36V DC range.

What does the alarm do on this gauge?
The display flashes an alarm when voltage drops below 10V, rises above 31V, or falls between 16–20V, alerting you to potential issues.

Does the gauge come with a wiring harness?
Yes, the package includes a set of cables with clearly marked red and black wires for power connections.

How do I install the oil pressure sensor?
The sensor uses a standard 1/8 NPT thread. You can install it into an available port on your engine block or use an adapter if needed.
