10 Best Digital Volt Meters 2025 in the United States

The Fluke 117 Digital Multimeter is designed for professionals who need a reliable and precise tool for various electrical measurements. One of its standout features is the VoltAlert technology, which allows for non-contact voltage detection, enhancing user safety. The AutoVolt function automatically selects AC or DC voltage, making it convenient to use. Additionally, its low input impedance helps prevent false readings, a common issue with ghost voltages. With a measurement accuracy of +/-0.5%, it delivers precise readings, which are crucial for detailed electrical work.

The large white LED backlight is helpful for working in dimly lit areas, ensuring visibility at all times. True RMS capability ensures accurate measurements on non-linear loads, which is essential for certain complex electrical systems. The device is also durable, with a robust plastic exterior designed to withstand the rigors of daily use. It has an impressive battery life of around 400 hours under typical usage conditions, which means less frequent battery changes and more uninterrupted work time.

However, it may be slightly heavy for some users at 550 grams, and its relatively high price point might be a consideration for those on a budget. The Fluke 117 also comes with a 3-year warranty, which provides peace of mind regarding its longevity and reliability. It measures resistance, continuity, frequency, and capacitance, and includes a Min/Max/Average function, making it versatile for a range of tasks. Despite being introduced in 2007, it remains a best-seller due to its reliability and comprehensive features. This multimeter is particularly well-suited for electricians, maintenance technicians, and other professionals who require a dependable and multifunctional tool.

The Fluke 117/323 Kit is a robust choice for both residential and commercial electricians. This combo kit includes both a multimeter and a clamp meter, catering to a wide range of electrical measurements. The 117 multimeter excels in accuracy with its true RMS feature, ensuring precise readings even on non-linear loads. It also boasts low input impedance, which helps in avoiding false readings due to ghost voltages. This is particularly useful for electricians dealing with complex wiring systems.

The 323 clamp meter complements the multimeter by offering accurate AC current measurements up to 400 A and voltage measurements up to 600 VAC/DC, making it suitable for high-demand electrical jobs. Both tools are battery-powered, adding to their portability and ease of use on various job sites. The inclusion of test leads, TPAK (toolpack), and a carrying case adds value by providing a complete set for immediate use and convenient transportation.

However, the kit's weight of 0.8 kilograms might be slightly cumbersome for those needing to carry it for extended periods. Additionally, while the display provides clear readings, the lack of advanced features like auto-ranging might be a drawback for some users who prefer more automated processes. Despite these minor inconveniences, the durability and reliability of Fluke devices are well-regarded, making this kit a dependable option for professionals.

The Fluke 323 Clamp Meter is designed for commercial and residential electricians, offering reliable measurements of AC current up to 400 amps and AC/DC voltage up to 600 volts. It also measures resistance up to 4 kilo ohms and provides audible continuity checks, which can be helpful for verifying circuit connections. One of its standout features is the true RMS sensing, which ensures accurate readings even when dealing with complex waveforms. This can be particularly valuable for professionals working with non-linear loads, as it maintains precision regardless of the waveform shape.

The jaw opening measures current without needing to touch the conductor, which enhances safety and convenience. It adheres to significant safety standards (IEC 61010) and is rated for CAT IV installations up to 300V and CAT III up to 600V, making it suitable for various environments and scenarios. However, the meter does not measure DC current, which could limit its use for certain applications. It has a decent resistance accuracy of 1.0% ± 5 digits, but this might not be sufficient for tasks requiring higher precision.

Durability is bolstered by a 2-year warranty and the inclusion of a soft carrying case, which adds value. The compact and lightweight design (200 grams) makes it easy to carry and handle during fieldwork. Though it requires 2 AAA batteries, these are included, ensuring the device is ready to use out of the box. In summary, the Fluke 323 is a robust and reliable tool for most electrical measuring needs, especially for tasks involving AC current and voltage, but it may fall short for professionals needing DC current measurements.
