Klein Tools MM720 Digital Multimeter – Auto-Ranging TRMS, LoZ, 1000V/10A

Klein Tools MM720 Digital Multimeter

The MM720 is a versatile, automatically ranging digital multimeter designed for professionals who value precise measurements and durable construction. It uses true RMS technology to provide reliable readings for both clean sine waves and more complex signals, while offering a wide range of tests in one compact tool.

What it measures and how it helps

• Voltage tests: AC and DC up to 1000V
• Current tests: AC and DC up to 10A
• Resistance: up to 60 MΩ
• Temperature, capacitance, frequency, and duty cycle
• Diode check and continuity testing for quick component verification
• Low impedance LoZ mode to identify ghost or stray voltages

Auto-ranging and TRMS technology ensure readings adapt to the signal being measured, reducing guesswork. The device also includes features to help you stay organized during fieldwork, such as test lead holders on the back, a built in kickstand, and an optional magnetic hanger for hands-free use.

Display and visibility

The large reverse-contrast LCD shines in bright sun or dim shop lighting, and an optical sensor automatically adjusts viewability for optimal readability. This assists during extended troubleshooting sessions and in varied work environments.

Practical uses and benefits

• Electrical maintenance and panel checks, from outlets to wiring runs
• On site electronics work where quick, multi-parameter checks save time

Designed with professional use in mind, the MM720 blends performance with practical features. Its rugged build and reliable measurements align with the needs of electricians, technicians, and DIY enthusiasts who demand accuracy without sacrificing durability.

Durability and reliability

With Klein Tools heritage and six generations of experience, the MM720 is built to withstand demanding environments while delivering consistent results for daily use. This tool embodies a commitment to precision and long-term reliability that professionals rely on.
