10 Best Digital Multimeters 2025 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 Fluke 117 Digital Multimeter is a solid choice for both professionals and DIY enthusiasts looking for a reliable tool for electrical testing. One of its standout features is the VoltAlert technology, allowing users to detect AC voltage without direct contact, which enhances safety and convenience. The automatic AC/DC voltage selection makes it easy to measure different electrical signals without manual adjustments, catering to varied needs in the field. With a true RMS capability, the Fluke 117 delivers accurate measurements even on non-linear loads, making it particularly useful for modern electrical systems.

In terms of specifications, it offers a decent measurement accuracy of +/-0.5%, which is suitable for most tasks. Its low input impedance helps eliminate false readings caused by ghost voltages, ensuring the reliability of measurements. The large LED backlight is a thoughtful addition, allowing you to work in dimly lit areas without straining your eyes.

The Fluke 117 is an excellent option for those who require precision and versatility in their measurements, particularly electricians and technicians. Its combination of features and dependable performance makes it a worthy investment.

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.
