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

This 0.28-inch Red Ultra-Small Digital 3.2-30V DC Voltmeter is a compact and reliable tool for monitoring DC voltage in real-time. Featuring a sharp red LED display, it is optimized for high visibility and low power draw, making it a perfect choice for automotive dashboards, motorcycle battery monitoring, and DIY electronics projects. The two-wire design is self-powered, allowing the unit to function using the same voltage it is measuring, which simplifies installation in 12V and 24V DC circuits. For professional-grade accuracy, the meter includes an automatic decimal point shift and a manual calibration potentiometer on the back. Integrated reverse polarity protection ensures the module is shielded from wiring errors, making it a safe and durable addition to any power system.

Key Features:

• Ultra-Miniature Design: Smallest form factor (0.28") for seamless integration into tight enclosures.
• Dual-Precision Display: 0.01V resolution for low voltage and 0.1V for higher voltage ranges.
• Wide Compatibility: Measures DC 3.2V to 30V, covering most battery chemistries.
• Reverse Polarity Safeguard: Prevents burnout if positive and negative leads are reversed.
• Onboard Calibration: Rear trimmer allows for fine-tuning against reference meters.
• Red LED Efficiency: High contrast for clear reading in both bright and dark conditions.

Package Includes:

1 x 0.28-inch Red Ultra-Small Digital 3.2-30V DC Voltmeter
