This is tiny and compact digital voltmeter with a red LED Display. The 0.28inch 0-100V DC three Wire Red LED Display 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 and the yellow/white wire is to connect to the positive pole of that source or another source across which we meant to measure the voltage. While measuring the supply voltage of another source make sure that negative pole is joined common. 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.
To reach the best measurement accuracy, this voltmeter will automatically move the decimal point position according to the different measuring voltage. When it measures the voltage below 10V, it will display two places after the decimal point. When it measures the voltage above 10V, it will display one place after the decimal point.
This voltmeter can be used to measure the storage battery’s voltage in motorcycles and cars and also can grasp the storage battery 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 permanent damage because of an electrical spark, power supply ripple, or other too high abrupt change of voltage.
Very bright and decent LED Display is ready to measure the dc voltages in the range of 3.6V to 28V.
Features :
- Very small and lightweight voltmeter module.
- Very handy and easy to use.
- Red LED display.
- Best operates in the working voltage range of 5V to 24V

Voltmeter are of good quality, has adjustable pot for fine tune if any chance reading gets off, so far its good working quality product, fast shipped, thanks
prisha singh –
I did not buy this yet? its still in my cart
Rakesh Kapoor –
Great ver fast service as per mentioned same day dispatch I m glad to order them

This can be used for measuring only upto 28vdc with single source.. If you connect 30v it will just go up in smoke. To measure anything higher than 28V you need a separate power supply to run the led circuit with common ground to the voltage source you need to measure. (0-100v).
