Voltio Digital Dc 2.5/3-40v Voltum Para Automóvil, Motocicle

Descripción

Feature:
1. The voltmeter has simple wiring, only two wires need to be connected, and there is anti connection protection in the voltmeter, which does not burn.
2. The starting voltage of this voltmeter is low. It only needs 2.5V for red, 2.7V for green and 3.0V for blue. The starting voltage of two-wire voltmeter at the same price can be called the lowest in the world. This will greatly facilitate the use of lithium batteries, 18650 batteries and other users. When the voltage is lower than 3.5V, the display brightness will darken, but it will not affect the correct measurement.
3. In order to achieve the best measurement accuracy, the voltmeter will automatically move the decimal point according to different measured voltages. When measuring the voltage below 10V, two digits are displayed after the decimal point; When measuring voltages above 10V, one digit is displayed after the decimal point. It can not only meet the needs of battery users for measurement accuracy, but also meet the needs of measuring higher voltage.
4. The voltmeter can be used to monitor the battery voltage of motorcycles and automobiles and master the battery status in time. It can also be used for other voltage measurement purposes.
