DC 12V 24V 52mm Car Voltage Gauge | LED Digital Voltmeter with Hour Meter

Key Features

• Moving-Magnet Drive — The needle is driven by a moving-magnet mechanism that resists vibration in rough conditions.
• Stepper Motor Design — The stepper motor uses less power and delivers higher precision.
• Anti-Fog Curved Glass — The curved glass has an anti-fogging function that keeps the display clear in damp environments.
• Wide Voltage Range — It operates from 9V to 32V, with a maximum of 36V for under one minute.
• Built-In Hour Meter — It tracks voltage and engine run time together in one gauge.

What It Is / How It Works

This DC 12V 24V 52mm car voltage gauge is a round LED digital voltmeter with a built-in hour meter. Voltmeters of this type show the electrical system voltage on a digital display, so drivers can check battery condition at a glance before starting the engine.

Who It's For / Use Cases

Dashboard voltmeters suit car and truck owners who want to watch battery voltage and charging performance. They also fit people who run boats, motorcycles, or farm and engineering machinery and want voltage and engine run time in one gauge.

How to Use / Care

1. Mount the gauge in a dashboard or instrument panel opening sized for a 52 mm round gauge.
2. Connect the red wire to the positive terminal and the black wire to the negative terminal.
3. Use it on a 12V or 24V system within the 9–32V operating range.
4. Read the LED display for system voltage and check the hour meter for engine run time.

How to Choose

Start with the system voltage: choose a gauge that covers 12V or 24V, as this one does. Check that your dashboard or panel has a 52 mm round opening.

Frequently Asked Questions

Does this gauge work on a 24V truck system?
Yes, it works on both 12V and 24V systems and supports a wide voltage range from 9V to 32V.

Can I use this gauge on a boat?
Yes, it is suitable for boats and marine applications thanks to its waterproof and anti-fog features.

What does the hour meter show?
It shows engine run time, with hours before the decimal point and minutes after the decimal point for maintenance scheduling.

Is the display easy to read in direct sunlight?
The LED digital display is bright and clear, and the curved glass helps reduce glare for better visibility.

Does it come with mounting hardware?
The package includes the voltmeter unit. You may need standard mounting brackets or a panel cutout for installation.
