Car Water Temperature Gauge with Voltmeter 2 in 1 | -10 to 110 Celsius LCD Display

Keep a close eye on your engine's vital signs with this 2 in 1 digital gauge. It combines a water temperature gauge and a voltmeter in one compact, easy-to-read LCD display. You get real-time data on both coolant temperature and battery voltage, helping you catch potential issues before they become costly repairs.

This gauge is built for universal fitment on 12V and 24V vehicles. It works with a wide power supply range of DC 9V to 36V, making it suitable for cars, trucks, SUVs, and vans. The digital display gives you precise readings, so you always know what is happening under the hood.

Installation is straightforward with the included water temperature sensor and adapter options. The kit comes with a 10mm sensor and adapters for 28mm and 34mm hoses, plus a 1/8 NPT sensor thread for flexibility. The gauge also features a flashing alarm to alert you when temperatures or voltage levels go out of range.

The plastic shell housing is durable and designed to resist vibration and bumps. Its round LCD screen is easy to read at a glance, even in low light. This gauge is a practical upgrade for anyone who wants more control over their vehicle's engine health without adding clutter to the dashboard.

• Flashing alarm feature that alerts you when readings go outside safe limits, helping prevent engine damage.

• Includes a water temperature sensor and adapter options for flexible installation in different hose sizes.

• Stable performance with low power consumption, so it won't drain your battery.

Who Is This For

- Car and truck owners who want a simple way to monitor engine temperature and battery voltage.

• DIY mechanics installing aftermarket gauges for better engine diagnostics.

• Off-road and work vehicle operators who need reliable data in tough conditions.

• Anyone replacing a broken or inaccurate factory temperature gauge with a modern digital unit.

Usage Scenario

Mark drives an older pickup truck he uses for weekend camping trips. Last summer, the engine overheated on a long hill climb, and he had no warning until steam came from the hood. After installing this 2 in 1 gauge, he now sees the water temperature and voltage at a glance. On a recent trip, the flashing alarm caught a rising temperature early, letting him pull over and let the engine cool before any damage was done. He says it feels like having a second set of eyes on the engine.

Micro Comparison

Many basic temperature gauges only show coolant temperature and use a needle or analog display that is hard to read precisely. This gauge gives you both temperature and voltage readings on a clear digital screen. The included sensor and adapter set also make installation more flexible than single-purpose gauges that require separate purchases for different hose sizes.
