10 Best Digital Multimeters 2026 in the United States

The Fluke 87V/IMSK Industrial Digital Multimeter is a comprehensive tool designed for industrial use, combining a multimeter with a current clamp kit to enhance functionality. Known for its accuracy, the Fluke 87V ensures reliable measurements in various applications, including temperature, frequency, and capacitance, with a peak min-max of 250 µs. Its resolution and range are suitable for detailed and precise readings, making it highly effective for professional use.

The inclusion of the Fluke i400 current clamp allows for AC current measurements up to 400A, broadening its scope of application. Its input impedance is designed to minimize interference, delivering precise readings across different measurement scenarios. Safety is a key focus, with robust safety ratings ensuring protection during high-energy measurements. The multimeter also comes with a limited lifetime warranty, indicating its durability and reliability in tough environments.

Additional accessories included, such as a temperature probe, test leads, and alligator clips, enhance its versatility and ease of use. However, the device's weight (355 grams) and size may be a consideration for users needing a more portable option. While the device is powered by 4 AA batteries (included), this could be seen as less convenient compared to rechargeable alternatives. The Fluke 87V/IMSK stands out in the digital multimeter category for its accuracy, range, and the added functionality of the AC current clamp, making it ideal for professionals in industrial and electronic applications.

The Klein Tools ET270 is a solid choice if you're looking for a versatile digital multimeter with some handy extras. It measures AC/DC voltage up to 600V and resistance up to 40 megaohms, which covers most household and light professional electrical tasks. Its auto-ranging function means you don’t have to manually select ranges, simplifying the measurement process, but you still have the option to switch to manual if needed. The meter offers good accuracy for general use, and its resolution is sufficient to catch subtle differences in readings.

One standout feature is the receptacle test mode that helps detect common wiring faults and tests GFCI receptacles, which adds an extra layer of electrical safety. It even shows GFCI trip time, useful for troubleshooting. Safety ratings include CAT III and CAT IV with protective caps on the test leads, meaning it’s designed to handle typical home and commercial electrical environments safely. The bright backlit LCD display improves visibility in darker spaces, and convenience features like test lead holders, a kickstand, and an optional magnetic hanger allow for hands-free operation, which is great when working alone.

It also includes a battery test for common household batteries and a circuit breaker finder mode, adding extra value beyond basic multimeter functions. The unit is powered by 2 AAA batteries, which are included, keeping it lightweight and portable. While it covers many bases, this model might not satisfy users needing very high precision or specialized functions found in more advanced meters. The Klein Tools ET270 is a user-friendly and reliable multimeter suited for homeowners, electricians, and DIYers who want a tool that goes beyond basic voltage and resistance measurements, with helpful safety and troubleshooting features included.

The AstroAI Digital Clamp Meter is a versatile tool suitable for both household and light industrial electrical work. It measures a wide range of values including AC/DC current and voltage, resistance, capacitance, frequency, and even performs live wire tests and non-contact voltage detection. The auto-ranging feature and 4000 counts resolution offer reasonably good accuracy for everyday tasks. The large clamp jaw allows easy current measurement without disconnecting wires, which is handy in tight spaces.

Safety-wise, it meets category III 600V standards, meaning it’s safe for most home and professional environments. Additional user-friendly features include a backlit LCD screen, flashlight for dark areas, data hold, and a zeroing function to improve accuracy by reducing magnetic interference. The non-contact voltage test with sound and light alerts adds an extra layer of convenience and safety.

The clamp function only measures current, so voltage must be measured in the traditional way using leads, requiring some care. Battery life depends on two AAA batteries, which are easy to replace but may need frequent changing depending on use. If you need a reliable, easy-to-use clamp meter with a good mix of features for general electrical troubleshooting, this model represents a solid choice, especially considering its price and support from a responsive customer service team.
