10 Best Dc Amp Clamp Meter 2025 in the United States

The AstroAI Digital Clamp Meter is a versatile and user-friendly tool suitable for both household and light industrial electrical tasks. It measures a wide range of electrical parameters including AC/DC current and voltage, resistance, capacitance, frequency, and continuity, making it quite flexible. Its jaw opening is designed to fit into narrow spaces comfortably, which is great for working in tight areas. The clamp meter features a clear backlit LCD display and a built-in flashlight, helping you read measurements even in poorly lit environments.

Non-contact voltage testing with audio and visual alarms adds a safety layer, alerting you to live wires without direct contact. It supports useful extras like data hold, max/min readings, and an auto power-off function to save battery life. The jaw opening is adequate but not very large, so it may not fit larger cables. Also, it runs on two AAA batteries, which are easy to replace but might need frequent changing depending on usage.

This clamp meter is a solid choice for general electrical troubleshooting and maintenance, especially for users who value safety features and easy handling, although professionals needing detailed specifications might seek additional information.

The Fluke 376FC AC/DC Clamp Meter stands out as a robust tool for industrial and commercial electricians. One of its key strengths is the ability to measure both AC and DC current, along with the inclusion of the iFlex current probe, which allows for measurements in tight spaces thanks to its flexible design. The jaw opening size is suitable for a variety of wire sizes, making it versatile for different applications.

Accuracy is another highlight, supported by the VFD low pass filter that enhances the precision of measurements, particularly useful when dealing with variable frequency drives. The Bluetooth connectivity feature adds significant convenience, allowing users to connect the meter to their smartphones and log, trend, and monitor readings remotely. This means electricians can maintain safety by staying at a distance when taking measurements, reducing the need for personal protective equipment (PPE).

However, there are some drawbacks to consider. The reliance on Bluetooth might not be ideal in environments with high electromagnetic interference, which could affect connectivity. Additionally, while the logging features are helpful, they might require a bit of a learning curve for those not familiar with using mobile apps for measurement logging. The display is clear, but it may not be large enough for users who prefer larger readouts for easier visibility, especially in bright conditions. The product is battery-powered, which is standard, but the requirement of 2 AA batteries may mean periodic replacements need to be factored into ongoing costs. The Fluke 376FC is an excellent choice for professionals seeking a reliable clamp meter with advanced features for remote measurement and fault logging. Its strengths in accuracy and convenient features make it well-suited for electricians in demanding environments, although some users may need to adjust to the technology aspects.

The Fluke 117/323 Kit is a solid choice for both residential and commercial electricians looking for a reliable multimeter and clamp meter combo. One of its standout features is the true RMS capability, which ensures precise measurements of AC and DC voltage and current, especially important when dealing with non-linear loads. The multimeter can measure AC and DC voltage and current, making it versatile for various electrical tasks. It also includes low input impedance to minimize false readings from ghost voltages, enhancing its reliability.

The clamp meter, which measures up to 400 A of AC current, adds extra convenience, allowing users to take readings without interrupting the circuit. The kit's accuracy of 0.5% + 2 is respectable, ensuring a good level of precision for most electrical work.

While the kit is compact and lightweight, some users might find the jaw opening size of the clamp meter limiting when working with larger cables. Additionally, being battery-powered means you’ll need to keep an eye on battery life, although it does come with batteries included. This kit is ideal for electricians needing reliable measuring tools for day-to-day work, but those requiring advanced features or more robust current capabilities might need to explore other options.
