Two Wire Voltmeter 0.36 inch DC 4.5-30V Digital Voltmeter

DESCRIPTION

This is tiny and compact digital voltmeter with a LED Display. The Two Wire Voltmeter 0.36 inch DC 4.5-30V Digital Voltmeter requires only a few minutes of configuration and is as simple as directly connecting wires to the source you want to measure and seeing the LED blink!!!!

The red wire is to connect to the positive pole, the black wire is to connect to negative pole. No need to worry even if there is any connection mismatch of the wires, the electric circuit won’t be a boom because it features reverse polarity protection.

This voltmeter can be used to measure the storage battery’s voltage in motorcycles and cars and also can grasp the storage battery’s status. It also can be used to measure other voltage. 30V is the voltmeter’s maximum operating limited voltage, please leave enough margin when working, to avoid voltmeter’s permanent damage because of an electrical spark, power supply ripple, or other too high abrupt change of voltage.

Very bight and decent LED Display is ready to measure the dc voltages in the range of 4.5V to 30V.

Features:

• Low cost, high accuracy and precision to meet most application requirements.
