Voltmeter DC 0,56 inch 0-30V

Detail Voltmeter DC 0,56 inch 0-30V

Features:
* 0.56''LED Digital Tube Wire DC 4.50-30.0V Voltmeter can be connected directly for measuring voltage
* You can use this meter to monitor voltage or battery of cars, vehicles, sailboat, RV, truck, race car, automotive, etc.
* With reversed connection protection, this item will not burn even when connected reversely , but its screen will display nothing
* Power supply range: No additional power supply , directly use the measured voltage as a power supply( the voltage range as above)
* The highest input is DC30.0V.
* The input voltage higher than 30V may be permanently damaged!
* With only two wires(the red and the black),simply connect the red to positive and black to the negative
* Its strong plastic case prevents it from easily damaged by outer force
* High-quality LED is adapted in this item, which is bright even in dim light
