    2 PCS 0.28" Digital Voltmeter Ammeter, DC 0-100V 10A 2 in 1 Volt Amp Meter with Connect Wires, Red & Blue Dual LED Display Panel Current Tester Voltage Gauge for EV Car Boat (10A)

    • Precision Monitor: Our LED voltage and current meter is specifically designed for accurate measurement of vehicle voltage and current. By monitoring the vehicle voltage and current conditions in real-time, you can ensure optimal protection for your car battery and extend its service time
    • LED Digital Display: Featuring a dual-color LED digital display, this voltage and current meter uses red to indicate voltage and blue for current. This intuitive design allows voltage and current readings to be displayed simultaneously, making them easy to read and distinguish
    • Reliable Material: Constructed with premium plastic housing and a durable electric board, our meter offers excellent rust and corrosion resistance for long-term use. It operates effectively across a temperature range of -10°C to 65°C, ensuring stable performance under various conditions
    • Product Specification: It measures 1.88"×1.14"×0.86", with a working voltage of DC 4-30V. It can quickly and accurately measure voltage in the range of 0-100V and current in the range of 0-10A. It also has a refresh rate of approximately 300 ms and a current consumption of 20 mA. Just to clarify, the 50A and 100A voltmeters need external shunt resistors to work, but we dont supply it

    What makes you select this LED digital voltmeter ammeter?

    -With its compact design, it is easy to store and carry, ensuring convenient access at any time.

    -It measures accurately with the margin of error for voltage measurement being 0.1%, and the margin of error for current measurement being 1%.

    -This digital voltmeter ammeter allows you to monitor your vehicle's voltage and current levels accurately and in real time, making it an essential tool when traveling.

    How to use this digital voltmeter ammeter?

    -When connecting the 1-10A meter head for direct power supply, connect the black thick wire to the negative pole of the power supply, and the red thick wire to the negative pole of the load. Connect the thin red wire and the thin yellow wire between the positive pole of the power supply and the positive pole of the load, and the thin black wire does not need to be connected.

    -When connecting a 1-10A meter head with an independent power supply, connect the black thick wire to the negative pole of the power supply, and the red thick wire to the negative pole of the load. Connect the thin red wire and the thin black wire to the power supply, and the thin yellow wire between the positive pole of the power supply and the positive pole of the load.
