10 Best Clamp Meters 2026 in the United States

The Fluke 376FC AC/DC Clamp Meter is designed for industrial and commercial electricians, offering a range of features that cater to their specific needs. It measures both AC and DC currents, with a robust current measurement range, making it versatile for various electrical applications. The inclusion of the iFlex current probe allows measurements in tight spaces, thanks to its flexible design. This can be particularly useful when dealing with complicated wiring setups.

One of the standout features is the True RMS capability, which provides accurate readings even for non-linear loads, a common scenario in modern electrical systems. The inrush measurement function helps to capture the initial surge of current, which is essential for diagnosing equipment behavior.

The Bluetooth connectivity is another significant advantage, allowing electricians to connect the meter to their smartphones. This feature means they can remotely log and monitor measurements, which enhances safety by keeping them at a distance while working on live circuits. The logging capabilities also make it easier to capture intermittent faults without needing constant supervision of the meter.

However, there are some potential drawbacks to consider. While the Fluke 376FC is packed with features, it may be more complex for beginners who aren't familiar with advanced measurements or smartphone connectivity. Additionally, its size could be a concern for those seeking a more compact tool, especially if they need to carry it around frequently. Display and readability are generally good, but in bright light, some users might find it challenging to view the readings clearly. Lastly, as with many professional-grade tools, it comes at a higher price point, which might not be justifiable for occasional users or DIY enthusiasts.

The Fluke 376FC is highly suitable for professionals needing a reliable and versatile clamp meter, particularly in industrial settings. Its advanced features cater well to those who require detailed and accurate electrical measurements.

The Fluke 378FC AC/DC TRMS Non-Contact Voltage Wireless Clamp is a solid choice for both professionals and DIY enthusiasts who require reliable and versatile electrical measurement tools. One of its standout features is the FieldSense technology, which allows users to measure voltage and current without needing to make direct contact with live wires. This not only enhances safety but also makes testing quicker and more efficient, especially in potentially hazardous environments. Furthermore, it provides true RMS measurements, ensuring accuracy when dealing with non-linear loads, which is crucial for diagnosing electrical systems accurately.

The clamp's capability to perform complete 3-phase voltage and current tests helps streamline the process, reducing the number of steps needed to gather essential readings. Additionally, the power quality indicator is a valuable feature, alerting users to any issues with the equipment or power line, thus facilitating proactive maintenance.

The display is generally user-friendly, but depending on the lighting conditions, visibility might be an issue for some users, especially in bright sunlight or dim settings. The Fluke 378FC is a feature-rich clamp meter that excels in safety and accuracy, making it suitable for various electrical testing applications.

The Fluke 375 FC True-RMS AC/DC Clamp Meter is a robust tool designed for accurate current and voltage measurements. It measures AC and DC current up to 600 A and voltage up to 1000 V, which suits a wide range of professional applications. The inclusion of True RMS technology ensures precise readings even with non-linear loads, which is beneficial for electrical troubleshooting.

A notable advantage is its compatibility with Fluke Connect, allowing users to connect the meter to a smartphone to read measurements from a safe distance. This reduces the need for extensive personal protective equipment (PPE) and enhances safety. Additionally, results can be recorded directly to the phone and the cloud, simplifying data management.

Another useful feature is the optional iFlex flexible current probe, which extends the measurement capability up to 2500 A AC, making this meter versatile for various tasks. The device is lightweight at 395 grams and comes with a soft carrying case for portability. The meter also boasts high safety ratings (CAT III 1000 V, CAT IV 600 V), ensuring it can be used in demanding environments. While it includes batteries, it may be worth considering the battery life for long-term use. This clamp meter is well-suited for professionals needing precise and safe distant measurements.
