What It Is / How It Works

This 2-in-1 car voltmeter has an LCD screen that shows two readings at once. It shows water temperature and battery voltage together, so one unit covers two readings that would otherwise need separate gauges.

Who It's For / Use Cases

Car owners who want to keep an eye on engine temperature and battery health will use it most.

Truck and SUV drivers who need monitoring on long trips or under heavy loads, and DIY mechanics fitting aftermarket gauges in project cars, also fit the intended use.

How to Use / Care

1. Confirm the vehicle runs a 12V or 24V electrical system before fitting the meter.
2. Use the meter in a daily driver, a truck or SUV on long trips, or a project car or restoration.
3. The LCD screen shows both readings at a glance, so you can check them while you drive.

How to Choose

Start with the electrical system of your vehicle, since the meter is made for 12V and 24V systems. Confirm the sensor thread is 10mm (0.39 in) before you buy. Choose this 2-in-1 unit if you want temperature and voltage on one display rather than two separate gauges.
