10 Best Digital Multimeters 2025 in the United States

The Fluke 117 Digital Multimeter is a solid choice for both professionals and DIY enthusiasts looking for a reliable tool for electrical testing. One of its standout features is the VoltAlert technology, allowing users to detect AC voltage without direct contact, which enhances safety and convenience. The automatic AC/DC voltage selection makes it easy to measure different electrical signals without manual adjustments, catering to varied needs in the field. With a true RMS capability, the Fluke 117 delivers accurate measurements even on non-linear loads, making it particularly useful for modern electrical systems.

In terms of specifications, it offers a decent measurement accuracy of +/-0.5%, which is suitable for most tasks. Its low input impedance helps eliminate false readings caused by ghost voltages, ensuring the reliability of measurements. The large LED backlight is a thoughtful addition, allowing you to work in dimly lit areas without straining your eyes.

The Fluke 117 is an excellent option for those who require precision and versatility in their measurements, particularly electricians and technicians. Its combination of features and dependable performance makes it a worthy investment.

The Klein Tools MM420 digital multimeter offers a solid mix of features suitable for general electrical work and DIY enthusiasts. It can measure AC/DC voltage up to 600V and current up to 10A, covering most common tasks. The inclusion of True RMS (TRMS) technology means it provides more accurate readings on complex signals compared to simpler meters. Auto-ranging makes it easier to use by automatically selecting the correct range, so you don’t have to guess.

The meter also measures resistance up to 50 MΩ and offers extra tests like temperature, capacitance, frequency, duty cycle, continuity, and diode checks, making it quite versatile. Klein Tools designs their meters with safe and standard input impedance suitable for most electronics work. Safety is enhanced with Lead-Alert, which lights up to confirm your test leads are correctly placed, helping avoid measurement errors or hazards. The backlit LCD is great for working in dim areas. Convenience features like lead holders, a kickstand, and optional magnetic hanger improve usability during hands-free tasks.

Powered by included AAA batteries and weighing about 14.5 ounces, the meter might feel a bit bulky compared to more compact models. It is suitable for electricians, technicians, and serious hobbyists who want a reliable, easy-to-use multimeter with plenty of functions without stepping into professional-grade pricing or complexity. Its safety ratings make it ideal for most common uses, though it may not be intended for very high-energy industrial environments.

The Fluke 87V Industrial Digital Multimeter is a strong option for those needing a reliable tool for advanced troubleshooting in industrial settings. One of its standout features is its accuracy, especially for frequency measurements on adjustable speed drives, thanks to its specially designed low-pass filter. This makes it particularly beneficial for professionals who work with complex electrical systems. The ability to capture intermittent signals quickly (as fast as 250 µS) with the Peak Capture feature adds to its utility in troubleshooting scenarios.

In terms of specifications, it measures up to 1000 V AC/DC, which covers a wide range of applications. The switchable high display resolution allows for 6000 to 20,000 counts, enabling users to see minute changes in readings, which is a definite plus for precise measurements. Additionally, it boasts excellent safety ratings (CAT III 1000V, CAT IV 600V), making it suitable for use in high-voltage environments.

The Fluke 87V stands out for professionals in industrial settings due to its advanced features and safety ratings, but those looking for something lightweight and user-friendly may want to explore other options.
