Can measure and display real-time voltage data between 8V and 16V DC. When the voltage is higher than the measuring range, 19.9 is displayed, and when the voltage is lower than 11.5V or higher than 19.8V, the number displayed on the voltmeter will flash and alarm. Large bright LED display, clear reading, waterproof and shockproof. Used to monitor battery voltage with reverse polarity protection. Determine the status of your battery between full charge and discharge in time. Widely used in automobiles, motorcycles, station automation, distribution automation, testing equipment, voltage stabilizers, etc.
