Product Description

🌟Monitor Your Vehicle Charging System This 52 mm digital voltmeter gauge provides real‑time DC voltage readings within 8‑18V working range, helping you observe the operating status of your alternator and battery. It shows concrete voltage values for your reference, so you can spot abnormal high or low voltage conditions at an early stage.
Clear Red LED Digital Display for Day & Night Use
Built‑in high‑contrast red LED digital screen delivers readable output under bright sunlight and dark driving environments. Standard 52 mm housing fits most dash pods, A‑pillar mounts and dashboard installation locations for quick visual checks while driving.
🌟Adjustable Over‑Voltage Audible Alarm Features user‑programmable over‑voltage alarm function. You can set your preferred trigger threshold (example:15.5V). When measured voltage exceeds your preset value, the built‑in buzzer will sound an audible warning to notify you of potential regulator‑related voltage spikes. Note: The alarm serves as driver reminder only; it cannot eliminate electrical component damage caused by system faults.
🌟Broad Application for 12V‑Based Vehicles Designed for 8‑18V DC electrical systems. Works for gasoline passenger cars, diesel pickup trucks, classic vehicles and RV set‑ups. It can be installed on dual‑battery configurations or vehicles fitted with high‑draw accessories such as winches and inverters. Not directly compatible with pure 24V systems without extra voltage reduction hardware.
🌟Durable ABS Housing Construction Heavy‑duty ABS housing is built to resist common under‑dash heat, vibration and UV exposure in normal automotive environments. After you finish alarm‑threshold setup, the unit will run automatically. Regular visual inspection of wiring connections is still recommended; it is not 100% maintenance‑free. 🔧 Important Notes: Measuring range: 8‑18V DC, do not apply voltage outside this working window.
Professional installation is highly recommended; wiring diagram is not included.
