Real-time voltage data can be measured and displayed with measurement range between 8V and 16V DC.Mini size with 3-digit LED digital display.Used to monitor storage battery voltage, with voltage protection. reverse connection. Timely grasp your battery status between full charge and discharge. Widely used for cars, motorcycles, bicycles, substation automation, distribution automation, test equipment, the voltage regulator and so on. When the voltage is lower than 11.5V or higher than 19.8V, the number displayed on the voltmeter will flash. It is designed for 12V cars or motorcycles. Large display and bright screen, waterproof and shockproof. The Car Digital Voltmeter is used to easily read your 12 volt system. Display 88.8 first, then back to display current voltage when connected to power. Mainly used to monitor car and motorcycle storage battery voltage and know storage battery working status. The voltmeter can also be used to measure the voltage of other products.Specifications:Type: Car Digital Voltmeter Display Type: 3 digital LED displaysDisplay color: blue / whiteMaterial: ABS Voltage measurement: DC 8V-16V Input voltage: 12V Accuracy: 0.2%Red Wire: Power supply +Black: power supply -Size: 56 * 29 * 10mm / 2.20 * 1.14 * 0.39inWeight: 27g / 0.95ozPackage Included:1 x LED Digital Voltmeter Note: The data are all manual measurement, please allow 1-3cm error, due to the light and display difference , there will be some color difference, depending on the physical item received.
