Zepkvor 3 Piece Digital DC Voltmeter 0.56" LED Panel Meter - ZEK-11

Monitor your batteries and circuits at a glance with the Zepkvor ZEK-11 Digital DC Voltmeter. This value pack includes three panel meters in three display colours - one red, one green and one blue - so you can colour-code every project, vehicle and test bench in your workshop.

The ZEK-11 measures DC voltage from 3.5V to 30V with 0.5% accuracy on a bright 0.56-inch three-digit LED display. It is a true 2-wire meter: the same two wires measure the voltage AND power the meter, so there is no separate power supply, no relays and no complicated wiring. Connect red to positive, black to negative, and the display lights up instantly with live readings that refresh every 300 ms.

The compact black housing drops straight into a standard 46 x 27 mm panel cut-out, and the snap-in clips hold it firmly in place - perfect for cars, motorbikes, trucks, e-bikes, boats, solar setups, power supplies, RC models and Arduino / ESP32 DIY projects.

KEY FEATURES:
3-Pack value set: 1 x red, 1 x green, 1 x blue display
