0.28-inch Blue Ultra-Small Digital 3.2-30V DC Voltmeter

This 0.28-inch Blue Ultra-Small Digital 3.2-30V DC Voltmeter is a robust and compact tool for precise DC voltage monitoring. Featuring a bright blue LED display, it is specifically designed for integration into vehicles, motorcycles, and portable battery projects where space is limited. The two-wire design is self-powered, allowing the unit to measure and display voltage from the same source, simplifying the wiring process. To ensure maximum accuracy, the meter features an automatic decimal point shift and a calibration potentiometer on the back for fine-tuning. Built-in reverse polarity protection ensures the module remains safe even if wired incorrectly during installation.

Key Features:

• Ultra-Compact Profile: At only 0.28 inches, it fits into the smallest project enclosures.
• Auto-Decimal Precision: Displays 0.01V resolution for sub-10V readings and 0.1V for higher voltages.
• Wide 3.2-30V Range: Perfect for monitoring 3.7V Li-ion, 12V Lead-acid, and 24V DC systems.
• Reverse Connection Protection: Protects the internal circuitry from wiring mishaps.
• Adjustable Calibration: Rear-mounted trimmer allows for manual accuracy correction.
• Low Current Draw: Consumes less than 20mA, making it suitable for sensitive battery setups.
