Features and Construction

This digital voltmeter is built for straightforward functionality and reliable voltage monitoring. Its anti-flame retardant material provides basic protection, while the waterproof LED lens keeps the display working in outdoor or humid environments. The unit measures DC voltage from 6 to 30V and is designed for use on 12V and 24V vehicles.

Material and Build

The voltmeter housing is made from anti-flame retardant material, which offers a level of fire resistance suitable for automotive and marine environments. The front features a waterproof LED lens that protects the digital display from moisture and splashes. Weighing only 13.6g, the unit is compact enough to mount on almost any flat surface without adding bulk.

Size and Practical Fit

At 13.6g and with a compact form factor, this voltmeter fits easily into standard dashboard cutouts, switch panels, or custom enclosures. The two included blue straight terminals simplify wiring, and the clearly marked polarity on the back of the unit helps avoid connection errors during installation.

Uses and Placement

This digital voltmeter is designed for any vehicle or equipment running on a 12V or 24V electrical system, including cars, SUVs, ATVs, and boats. Its waterproof lens makes it suitable for outdoor and marine use, while the bright LED display ensures readability even in daylight.

Automotive and Marine Use

Mount the voltmeter on your dashboard, centre console, or instrument panel for quick voltage checks while driving or boating. For off-road vehicles and ATVs, it helps you monitor battery load during winch or accessory use. On boats, the waterproof lens handles spray and humidity without issue.

Workshop and DIY Projects

Beyond vehicles, this voltmeter is useful for monitoring battery voltage in solar setups, power supplies, or backup systems. The 6-30V measuring range covers most small to medium DC power sources, and the anti-flame retardant casing adds a layer of safety when installed near sensitive electronics.
