12 Volt Digital Voltmeter, DROK 0.56' DC 3-30V 12v Voltage Tester Gauge Green Bright LED Display Two Wires Volt Meter Detector for Solar Battery Monitor Checker Car Motor Panel Mount

• High accuracy: DROK digital voltmeter measuring range is DC 3-30V, its decimal point will automatically move, and it also has a tiny potentiometer to do finer adjustments.
• Easy to connect wires: the voltage tester gauge only has two wires, the red connects to positive and the black connects to negative.
• Safe to use: our volt detector is designed with reversed connection protection, it will NOT be burnt even when connected reversely, but the screen display nothing.
• Special Design: the voltage mintoring meter is designed with bright LED display, and it is well Made, the strong plastic case prevents it from easily damaged by outer force.
• Application: It is perfect to monitor the condition of the battery, especially for solar projects, you can use it on your car, trailer, motor, etc. Please don't use this meter in 24V battery because when the battery is full-charged, its voltage will be about 30V.
