Monitoring Function: Voltmeter Gauge is widely used at DC 12-24 V with an accuracy of 0.1V. When the car voltage is displayed at 13.4-14.8 V, it indicates the normal voltage after starting, and when 12.2-12.8 V, it indicates the normal voltage without starting. If the value is lower than 12 V, replace the battery. It can timely grasp the state of the battery between full charge and discharge

Digital Monitoring: These waterproof voltmeters are equipped with a 3-digit precision LED digital display, facilitating effortless reading. They enable real-time monitoring of battery voltage, allowing for a clearer understanding of battery status and ensuring a safer driving experience

Premium Material: These voltage panels are constructed from copper and PC flame-retardant materials that exhibit resistance to heat. The high-quality materials is characterized by its strength, wear resistance, waterproof and low flammability, which posses a high safety factor, supporting long-term application

Easy to Install: This 12V voltmeter is designed for plug and play installation and is very easy to install. Simply place the panel into the 1 1/8 "hole and secure the instrument panel into place with the supplied nylon retaining nut

Wide Application: The voltmeter is suitable for DC 12V 24V vehicles, which can meet your different needs and is practical. Widely used in boats, boats, cars, motorcycles, trucks, ATV, UTV, cars, campervans, caravans and so on
