Description
Overview
A round panel-mount voltmeter with a bright LED digital readout, made to sit in a dashboard cut-out and be read at a glance. It is waterproof, with blue, red or green digits in a DC 3.3-30V or DC 12-24V range.
Specifications
- Display: LED digital numeric
- Range: DC 3.3-30V or DC 12-24V, by variant
- Colours: blue, red, green
- Body: round, panel mount
- Sealing: waterproof
- Serves 12V and 24V systems
Purpose
Charging and battery faults show up as a drifting voltage long before anything stops working. A permanently fitted gauge keeps that number in view.
Applications
- Car, van and truck dashboards
- Motorcycle battery monitoring
- Camper and boat panels
- Solar battery-bank displays
- 12V and 24V pump or winch setups
How to Use
- Pick the range bracketing your system: DC 12-24V for vehicles, DC 3.3-30V for wider coverage.
- Choose digit colour, cut a round hole to suit the body, seat the bezel.
- Positive lead to the measured point, negative lead to ground.
- Compare against a trusted meter at rest and under load.
- Stay inside the rated range; a 12-24V unit on a higher-voltage bank will be damaged.
