【Excellent material】: The car voltmeter is made of high quality durable plastic ABS. ABS plastic is durable and robust, wear-resistant, not easy to burn, with a high safety factor, ensuring long-term use. It is also waterproof, so it can withstand harsh weather conditions such as rainy days. 【Detection and protection】: The car voltmeter is able to accurately monitor the voltage of the car battery in the range from 5 V to 25 V and capture the voltage status of the battery in a timely manner. This allows you to quickly take action before potential problems occur to prevent failures and improve safety. In addition, equipped terminals can protect the power line and prevent overloading of fuses. There are 3 different colors on the display screen indicating different voltage states, making it easy to read and understand the condition of the car battery. 【What you get】: The packaging is one-piece. The one-piece package includes a 1 digital voltmeter with LED DC and 2 isolated terminals display. 【Good Application】: 37 caliber mm digital LED voltage meter with 40 mm length with terminals can be widely compatible with most types of DC 12V vehicles that include cars, motorcycles, trucks, ships, boats and so on. It is an essential accessory for detecting the battery voltage of your vehicle in real-time.
