10 Best Dc Amp Clamp Meter 2025 in the United States

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 377FC AC/DC TRMS Non-Contact Voltage Wireless Clamp w/iFlex is a versatile tool designed for both professional and industrial use. One of its key strengths is the incorporation of FieldSense technology, which allows users to measure voltage and current without directly contacting live wires, enhancing safety and efficiency. This is particularly useful for those working in environments where safety is paramount.

Additionally, its ability to perform complete 3-phase voltage and current tests with fewer steps can save time and reduce complexity in multi-phase systems. The wireless capability, facilitated by Fluke Connect software, allows for logging, saving, and sharing readings, which is ideal for maintaining records and collaborating with team members remotely. The device is relatively lightweight at 454 grams and portable, making it convenient for on-the-go use.

It is powered by 2 AA batteries, which are included, ensuring that it is ready to use out of the box. The display is clear and user-friendly, which is essential for reading measurements quickly and accurately. However, potential drawbacks include the reliance on battery power, which might necessitate frequent replacements depending on usage. Additionally, while the iFlex feature enhances flexibility and measurement range, it might add to the learning curve for those unfamiliar with such technology. Despite these minor concerns, the Fluke 377FC stands out as a robust and reliable choice for those needing precise and safe measurement capabilities in both AC and DC environments.

The Fluke 381 Remote Display True-RMS AC/DC Clamp Meter is a versatile tool designed for accurate current and voltage measurements. It stands out due to its True-RMS capabilities, which ensure precise measurements even with non-linear signals, making it suitable for complex electrical environments. The jaw opening size and iFlex flexible current probe allow for a wide current range measurement up to 2500 A AC, accommodating a variety of professional tasks.

The backlit display is large and automatically adjusts the measurement range, simplifying usage without frequent adjustments. Additionally, the display is detachable and wireless, providing added convenience by allowing it to be viewed from up to 30 feet away, which can be particularly useful in hard-to-reach areas or for monitoring from a distance. The integrated low pass filter also enhances performance in noisy electrical environments, ensuring stable readings.

However, the device is relatively heavy at 16 ounces, which might be cumbersome for prolonged use. Additionally, it is battery-powered, so users need to manage battery life during extended tasks. The included soft carrying case adds to portability, but some users might prefer a more robust case for added protection. This clamp meter is particularly well-suited for professionals in electrical and HVAC fields who require precise and flexible measurement options. Despite the few drawbacks, the Fluke 381 offers a great blend of accuracy, flexibility, and user-friendly features.
