0.28 Inch Digital DC Voltmeter 2.5 To 30 Volt Adjustable Voltage Tester For Car Mobile Power With Red Green Blue Display

Two wires, convenient and simple wiring, easy to connect to the car / battery car / motorcycle internal circuit, with reverse connection protection function, the reverse connection will not be burned, with fine adjustment function;

Extreme working conditions: Low working voltage: + 2.4V Maximum working voltage: + 40V Working temperature: -10 ～ + 65 ℃ Operating humidity: 10 to 80% (non-condensing) Working pressure: 80 ～ 106kPa Sun exposure: no direct exposure Measurement accuracy. The voltmeter will automatically move the position of the decimal point according to the measured voltage. When measuring voltage below 10V, two digits will be displayed after the decimal point; When measuring voltage greater than 10V, one digit is displayed after the decimal point. It can take care of the needs of battery users for measurement accuracy, and can also take care of the need to measure higher voltages. This voltmeter can be used to measure the voltage of 18650 batteries, mobile phone lithium batteries, nickel-metal hydride batteries and other battery packs. As well as the voltage of batteries such as motorcycles and automobiles, it can also be used for other voltage measurement
