6 PCS Mini Voltmeters 0.28'' 0-30V Red
This voltmeter has simple wiring and convenient use, with two connection modes of 2-wire and 3-wire.
It can directly work in 5V, 9V, 12V, 24V and other circuits without voltage regulation.
Equipped with three wires, convenient to connect to the car/battery car/motorcycle wiring, with reverse connection protection function, the wire will not be burnt when connected reversely.
When measuring voltage below 10V, two digits after the decimal point; when measuring voltage above 10V, one digit after the decimal point.
Note that it cannot exceed 30V, it may be damaged if it exceeds 30V.
