10 Best Multimeters 2025 in the United States

The Fluke 117 Digital Multimeter is a solid choice for both professionals and hobbyists in need of reliable electrical measurements. One of its standout features is the VoltAlert technology, which allows for non-contact voltage detection, enhancing safety when working with electrical systems. Its AutoVolt function automatically selects between AC and DC voltage, making it user-friendly and efficient. With a measurement range of up to 600.0 mV and a resolution of 0.1 mV, the multimeter delivers great precision for various applications.

Another strong point is its True RMS capability, which improves accuracy when measuring non-linear loads, a common scenario in modern electronics. The low input impedance helps prevent false readings due to ghost voltage, ensuring users get reliable data. Additionally, the large LED backlight is a practical feature for working in dimly lit areas, enhancing usability.

The device is highly accurate with a measurement accuracy of ±0.5%, but it may not meet the needs of users looking for exceptionally high precision in specialized applications. The weight of 1.21 pounds makes it slightly heavier than some other multimeters, which could be a consideration for those who prioritize portability. Furthermore, it relies on battery power, which, while convenient, means that users need to keep an eye on battery life, although it boasts an impressive 400 hours of usage without backlight.

The Fluke 87V Industrial Digital Multimeter is a solid choice for professionals and serious hobbyists who need precise and reliable measurements in demanding environments. It stands out for its accuracy and resolution, offering up to 20,000 counts, which means it can detect very small changes in readings—ideal for detailed troubleshooting. Its range is impressive, measuring AC and DC voltages up to 1000 volts, suitable for industrial and advanced electrical work. The built-in low-pass filter helps get clean frequency measurements on devices like adjustable speed drives, and the Peak Capture feature can catch very brief electrical events, which many basic meters miss.

Safety is a priority here, with high safety ratings (CAT III 1000V, CAT IV 600V) that protect users when working on high-energy circuits. Included accessories like test leads, alligator clips, and a temperature probe add convenience and versatility. However, it runs on four AA batteries, which might require frequent replacement in heavy use. While it’s a bit heavier and larger than simpler models, this reflects its rugged build quality and advanced functions.

If you need a reliable, feature-rich multimeter for industrial or complex troubleshooting tasks, the Fluke 87V is an excellent tool that balances precision, safety, and practical features.

The Fluke 323 Clamp Meter is designed with both commercial and residential electricians in mind. It excels in measuring AC current up to 400 amps and AC/DC voltage up to 600 volts, making it a practical choice for various electrical tasks. One of its strengths is the true RMS sensing, which ensures accurate readings for both linear and non-linear loads—even with complicated waveforms. This feature is particularly beneficial in today's diverse electrical environments.

The clamp meter's jaw opening allows it to measure current in a conductor up to 30 millimeters without the need to break the circuit, which adds convenience and safety during measurements. It also includes an audible continuity sensor, which is helpful for quickly determining if a circuit is conductive.

In terms of safety, the Fluke 323 meets IEC safety standard 61010 1, and its CAT IV and CAT III ratings provide confidence when working in various environments. However, it does not measure DC current, which could limit its usability for some users who need to work with DC systems. The resistance measurement is limited to 4 kilo ohms, which is adequate for most residential applications, but some professional electricians may require a higher range. The meter is lightweight at 200 grams and comes with a soft carrying case, enhancing its portability.

The Fluke 323 is a solid option for electricians and DIY enthusiasts; those needing to measure DC current or more extensive resistance ranges should explore other models. For general AC measurements and residential projects, it stands out as a reliable tool with good accuracy and ease of use.
