Compact 3-digit Blue LED Voltmeter

The Stetsom Mini Voltmeter is an ultra-compact panel meter with a blue 3-digit LED display. It measures DC voltage precisely from 7V to 30V and weighs 12.8 grams. The unit fits a 1.87 x 0.79 x 0.51 inch cutout for clean dashboard or console mounting.

For 12V audio installers, not AC or data logging

Installers adding amplifiers or processors to a 12V vehicle system can verify supply voltage at a glance. The meter requires DC input within the 7V to 30V window and provides no data logging, alarms or AC measurement. Users needing historical records or mains voltage readings should look at other instruments.

7V to 30V DC measurement range decides fit

The single specification that determines compatibility is the 7V to 30V DC operating window. Your vehicle or audio system must operate inside this range for the display to function correctly. Confirm the nominal system voltage before purchase.

Questions about this item

What does the 7 V to 30 V range mean when the meter is installed in a vehicle?

The display will show battery voltage as long as the supply stays between 7 V and 30 V; below 7 V the meter cannot power up, and above 30 V it may be damaged.

What connection standard does the voltmeter use and what does it limit?

It connects with two simple DC wires, so the only practical limit is the 7 V–30 V measurement window — no data bus or protocol is involved.

What cut-out size is needed to panel-mount the 1.87 × 0.79 × 0.51 inch case?

Allow roughly 1.9 × 0.8 inches for the rectangular body; the 12.8 g unit can also be surface-mounted with double-sided tape or a small bracket.
