A Digital Multimeter (DMM) is a compact, multi-functional electronic measuring instrument designed to accurately test voltage, current, resistance, and a variety of additional electrical parameters. Unlike analog models, digital multimeters display results on a high-contrast LCD screen, ensuring easy readability and improved measurement accuracy.

This all-in-one diagnostic tool is a staple in electronics, electrical maintenance, industrial environments, and educational labs. Advanced models come with features such as capacitance, frequency, diode, temperature, and continuity testing—making them indispensable for both beginners and professionals.
