10 Best Volt Meters 2026 in the United States

The Fluke 117/323 Kit is designed for both residential and commercial electricians, offering a combination of a multimeter and a clamp meter. One of its main strengths is its accuracy, especially with true RMS technology, which ensures precise measurements on non-linear loads. This is critical for accurate readings in complex electrical environments.

The resolution and range are also commendable, with the multimeter able to measure both AC and DC voltage and current, and the clamp meter handling up to 400 A for AC current and 600 V for both AC and DC voltage. This range covers most needs for electricians working in various settings. The low input impedance of the 117 multimeter is particularly beneficial as it reduces the risk of false readings due to ghost voltage, making it more reliable. However, one potential drawback is that it might be considered overkill for basic home use due to its advanced features and capabilities.

Additional features like the included test leads, TPAK (magnetic hanger), and carrying case add to its convenience and portability. This kit is a robust and reliable choice for professional electricians who need accurate, versatile tools for a wide range of applications. Beginners or casual users might find it more advanced than necessary for everyday tasks.

The Fluke 117 Digital Multimeter is a battery-powered device designed to measure various electrical parameters, including resistance, continuity, frequency, capacitance, and both AC and DC voltage. One of its standout features is the VoltAlert technology for non-contact voltage detection, making it safer and easier to use. The AutoVolt automatic AC/DC voltage selection simplifies the operation by automatically choosing the correct mode, and the low input impedance feature helps to prevent false readings caused by ghost voltage, enhancing measurement accuracy.

This multimeter has a measurement accuracy of +/-0.5%, which is quite reliable for most needs. The resolution and range are also quite commendable, with a DC millivolt range up to 600.0 mV and a resolution of 0.1 mV, making it suitable for delicate measurements. Its large, white LED backlight ensures visibility in poorly lit areas, and the True RMS function allows for accurate measurements on non-linear loads, which is useful for modern electrical equipment. At 550 grams, this multimeter is relatively heavy and may not be the most portable option.

The device includes a 3-year warranty, which adds to its reliability. Another downside could be its battery life; although 400 hours is quite substantial, frequent users might find themselves changing batteries more often than desired. The Fluke 117 is a versatile and reliable multimeter suitable for both professionals and serious DIY enthusiasts.

The Fluke 323 Clamp Meter is a reliable tool designed for both commercial and residential electricians. It measures AC current up to 400 amps and AC/DC voltage up to 600 volts, making it versatile for various electrical tasks. One of its major strengths is the True RMS sensing feature, ensuring accurate readings for both linear and non-linear loads. The meter also measures resistance up to 4 kilo ohms and offers an audible continuity sensor, which helps confirm if a circuit is conducting electricity.

Additionally, it meets stringent IEC safety standards and is rated for CAT IV installations up to 300V and CAT III installations up to 600V, indicating high safety levels for professional use. The jaw opening can measure current in a conductor up to 30 mm without interrupting the circuit, enhancing its convenience and safety further. The device is lightweight at 200 grams and comes with a soft carrying case and a 2-year warranty, adding to its portability and reliability.

However, it does not measure DC current, which might limit its use for some specific applications. Also, being a corded electric device powered by two AAA batteries, it might require regular battery replacements. Despite these minor drawbacks, the Fluke 323 Clamp Meter stands out for its high accuracy, robust build, and essential features, making it a strong choice for professional electricians.
