Car Digital Voltmeter 12V LED Display Waterproof Voltage Gauge Meter

Alarm Function: When the voltage falls below 4 Volts, the display will show "L L L" as a warning. When the voltage exceeds 28 Volts, the display will show "H H H" to alert you.

Waterproof Design: The voltage gauge meters feature a smooth surface design that is waterproof. The PVC material used allows for a transparent shell, making it easy to see the screen clearly.

Versatile Usage: This product includes 2 voltage gauge meters, making it suitable for multiple purposes such as cars, ships, RVs, substation automation, distribution automation, and test equipment. It is designed to meet a variety of needs.

DC 4-28V Car Digital Voltmeter Gauge: The voltage detection is done through two wires, eliminating the need for a separate power supply. The mini-sized meter features a 3-digit LED digital display, providing easy connection and waterproof capabilities.

Extreme Working Conditions: The meter is designed to withstand harsh conditions, with a working temperature range of -10 to +70 ℃ and a working humidity of 10 - 80%. It can handle a working pressure of 80 - 106 kPa and should not be exposed directly to sunlight to prevent damage.

Operating Voltage: The meter operates on a voltage range of DC 4 - 28 Volts. It will display "L.L.L." when the voltage is below 5 Volts and "H.H.H." when the voltage exceeds 19.9 Volts.
