2-in-1 Engine Temperature Gauge and Voltmeter – Keep a constant eye on your engine’s vitals
An overheating engine leaves you with very little reaction time. A delay of just a few seconds can lead to catastrophic damage—and a hefty repair bill. With this digital engine temperature gauge and voltmeter, you can monitor two critical parameters simultaneously: coolant temperature and battery voltage. Everything you need to know, displayed clearly on one screen.
Note: The temperature sensor (10 mm diameter, 300 cm cable) is included in the box. Please verify your mounting hole diameter before installation for a perfect fit.

Frequently Asked Questions
Does it work on both 12V and 24V systems?
Yes. The operating range is 9V–36V DC, making it compatible with cars and motorcycles (12V) as well as trucks, tractors, and heavy machinery (24V) without any modifications.
Is the sensor included or sold separately?
It is included in the box—a 10 mm diameter sensor with a 300 cm cable. You have everything you need to get the gauge working right out of the box.
What happens when the temperature hits 95°C?
The gauge automatically triggers a visual alarm. This gives you enough time to pull over or reduce the engine load before the motor enters the danger zone.
Is the display visible in direct sunlight?
Yes. The integrated sun visor ensures the screen remains easy to read in bright conditions, including when working outdoors in the summer.
Will it work on a truck or large agricultural machine?
Absolutely. The 300 cm sensor cable is designed to bridge the long distance between the engine and the dashboard in larger vehicles, and the 24V power supply is fully supported.
