Ten voltmeters in five colours

This pack contains ten mini DC voltmeters supplied in red yellow blue green and white with two units of each colour. They are intended for DIY builders and automotive hobbyists who need a compact voltage readout on multiple projects or battery banks at once.

0.28 inch LED panel with 3-wire connection

Each meter uses a 0.28 inch LED display driven by 28AWG leads that are 19.5cm long and fits a 23 by 10mm cut-out. The three-wire harness lets you power the display from the measured circuit or from a separate source while reverse-polarity protection prevents damage if the leads are swapped.

Replaces single-colour gauges when colour coding

The multi-colour set upgrades installations that previously relied on identical meters and makes it easier to identify circuits at a glance. It is not suited for users who only need one meter or who require a display larger than 0.28 inches.

Questions about this item

What does the three-wire connection limit for this 0-100V voltmeter?

With red and yellow paired for positive, the maximum readable voltage is 40V; to reach 100V the yellow wire must connect to a separate source of 40V or less.

What panel cut-out does each 0.28 inch Sumklin meter need?

Each unit requires a rectangular hole of approximately 23 mm by 10 mm for panel mounting.

How are the three wires of this DC voltmeter wired for a basic voltage reading?

Connect red and yellow together to the positive supply, black to negative; the display refreshes roughly every 200 ms and draws under 30 mA.
