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 Extech 380560 High Resolution Precision Milliohm Meter stands out with its high accuracy and resolution, making it suitable for precise electrical measurements. Its 4-in-1 DC power supply feature is a notable advantage, as it combines two fully adjustable supplies with two auxiliary outputs. This means you can handle a variety of power needs, from 0 to 30V/0 to 5A with selectable constant voltage and current modes, to fixed outputs with 3 to 6.5V/3A and 8 to 15V/1A.

The versatility can be quite beneficial in a lab or industrial setting where different ranges of power are required. The size and weight (11 x 3.5 x 8.3 inches; 4.85 pounds) make it somewhat bulky, potentially a drawback for those needing a more portable solution. Additionally, being an older model, it may lack some of the advanced features found in newer devices.

However, its robust build and the reputation of Extech Instruments suggest reliability and long-term use. This milliohm meter is ideal for professionals in industrial and scientific fields who need a reliable and versatile tool for precise measurements.
