DC2.5V-30V Digital Voltmeter Voltage Tester Meter 0.28" LED Volt-Instrument Tool 2 Wires 3-Digit Display Voltmeter Gauge

Features: Widely application. Wide voltage work, red minimum measured voltage 2.5V, maximum safe pressure up to 30V, more than 30V May be damaged. Conventional without external working power- supply, can use the measurement voltage directly work, measurement voltage ranges two-line 2.5-32V. When measuring the voltage below-10V, two digits- are displayed after the decimal-point; When measuring voltage above 10V-, one digit- is displayed after the decimal-point. The voltmeter connection is simple, conventional use of two wires, red connection positive, black connection- negative, there is reverse connection protection, reverse connection is not burning.
