10 Best Multimeters 2025 in the United States

The Fluke 117/323 Kit is designed for both residential and commercial electricians, making it a solid choice for anyone needing reliable electrical measurements. This combo includes a multimeter and a clamp meter, offering versatility for various tasks. The 117 multimeter provides true RMS measurements, which is essential for accurate readings on non-linear loads, and it also features low input impedance to reduce false readings from ghost voltage. It measures AC and DC voltage and current, making it comprehensive for electrical diagnostics.

The 323 clamp meter complements the multimeter well, with the ability to measure up to 400 A of AC current and 600 VAC and DC voltage, which should satisfy the needs of most electricians. Both tools have excellent safety ratings, ensuring use is safe even in challenging environments.

On the downside, the accuracy rating of 0.5% can be a bit limiting for precision work, especially in situations where high accuracy is critical. Additionally, its reliance on 9V batteries may necessitate regular replacements, and while batteries are included, the ongoing cost could be a minor inconvenience. The combination kit is slightly heavier at just under 2 pounds, which may be a consideration for users who need to carry it around frequently.

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 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.
