10 Best Digital Multimeters 2025 in the United States

The AstroAI Digital Clamp Meter is a handy tool designed mainly for measuring AC current using its clamp feature, plus AC/DC voltage, resistance, capacitance, and continuity. It offers auto-ranging and a 2000 count display, which means it gives reasonably detailed readings suitable for most home or light industrial electrical troubleshooting. The meter’s non-contact voltage (NCV) feature adds a safety layer by alerting you to live wires via sound and light without touching them. One important limitation is that it cannot measure DC current, so if you need that, this isn’t the ideal choice.

Its accuracy and resolution are typical for this price range, providing enough detail for everyday electrical tasks but not for precision lab measurements. The device is thoughtfully designed with features like data hold, max/min recording, backlit screen, and a built-in flashlight, making it easier to use in dim or tight spaces. Safety-wise, it meets category III 600V standards, meaning it’s safe for most household and industrial electrical environments.

Powered by two AAA batteries, it’s lightweight and portable. If you mainly need a reliable and affordable clamp meter for basic AC current and voltage checks with added convenience features, this model fits well. For advanced or DC current measurements, other options may be more suitable.

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.
