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 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 17B+ Digital Multimeter is designed for a broad range of electrical applications, which makes it quite versatile. One of its major strengths lies in its accuracy and range, with the ability to measure AC/DC voltage up to 1000V and current up to 10A. This makes it suitable for both household and industrial use. Additionally, it covers key measurements such as resistance, continuity, capacitance, diode testing, and temperature, offering a comprehensive toolkit for troubleshooting various electrical issues.

The inclusion of a type K thermocouple for temperature measurement up to 400C is a notable feature for those working with heating and cooling systems. The CAT III 600V safety rating is a critical safety feature, ensuring protection while working on electrical systems in different environments. Its input impedance is designed to give accurate readings without affecting the circuit, which is important for precise measurements.

There are a few drawbacks. The product's weight (450 grams) might be on the heavier side for some users who prefer lighter tools for prolonged use. The battery-powered nature of the multimeter means that ensuring you have spare batteries is crucial to avoid downtime. Additionally, some users may find the lack of advanced features like Bluetooth connectivity or data logging a limitation, especially for more complex tasks requiring detailed records over time. Despite these minor drawbacks, the Fluke 17B+ stands out as a reliable, accurate, and safe tool for both professionals and DIY enthusiasts needing a robust multimeter for various electrical applications.
