10 Best DC Clamp Meters 2026 in the United States

The Fluke 378FC is a versatile and reliable clamp meter designed for both AC and DC current measurements up to 1000A, making it suitable for a wide range of electrical testing tasks. It stands out with its FieldSense technology, which allows you to measure voltage and current safely without directly touching live wires—great for faster and safer testing. The jaw opening is large enough to fit around cables and wires comfortably, helping with ease of use in different environments. The meter provides True RMS (TRMS) readings, which means its measurements are accurate even with complex electrical signals.

It also features a clear display and wireless connectivity, so you can read measurements remotely via an app—handy for troubleshooting in tight or hard-to-reach spots. Another useful feature is the power quality indicator that helps identify problems with electrical equipment or power sources quickly. The meter is somewhat bulkier and heavier than simpler models, which might be a consideration if you need a very lightweight tool.

Offering high accuracy and advanced features, this model is ideal for electricians and technicians looking for safety, accuracy, and smart features in a clamp meter, especially when working on complex electrical systems or three-phase power setups. However, those who only need basic current measurements might find this model more advanced and pricier than necessary.

The Fluke 902 FC HVAC True-RMS Clamp Meter is designed especially for HVAC professionals, offering precise measurements that include microamp DC current, which is useful for tasks like measuring flame rods. It provides True-RMS readings, ensuring accuracy even with complex electrical signals, and can measure resistance up to 60 kiloohms, which covers a wide range of thermistors. The jaw opening size is practical for everyday HVAC work and allows for easy clamping around wires.

The meter also features a clear display and can capture flue gas temperature up to 400°C, adding to its versatility. One standout feature is its Bluetooth connectivity through Fluke Connect, letting you send measurements directly to your smartphone, which helps with safety and efficiency on the job. Weighing just over 400 grams, it’s portable enough for fieldwork and comes with useful accessories like test leads, a temperature probe, and a carrying case.

While the device is strong on HVAC-specific measurements and accuracy, it might be more than needed for general or casual electrical use, and its price could reflect that professional focus. For those who need a reliable clamp meter with specialized HVAC features and smart connectivity, this unit represents a solid choice.

The Fluke 376FC AC/DC Clamp Meter is designed for industrial and commercial electricians, offering a robust current range with the included iFlex probe, which allows measurements of AC/DC currents up to 1000A. Accuracy is enhanced by the VFD low pass filter, ensuring precise readings even in noisy electrical environments. The resolution is sufficient for detailed measurements, and the jaw opening size is ample, making it easy to clamp onto various conductors.

The display is clear and easy to read, which is crucial for quick and accurate data interpretation. Additionally, the Bluetooth connectivity allows remote monitoring and logging of measurements, which is a significant advantage for safety and efficiency, as electricians can view readings from a safe distance and perform other tasks simultaneously. The ability to capture intermittent faults and share reports in real-time is particularly useful in complex industrial settings where downtime is costly.

However, the meter is relatively heavy at 395 grams and may be cumbersome for prolonged use. The reliance on battery power means electricians need to ensure they have spare batteries on hand, which could be seen as a minor inconvenience. Despite these drawbacks, the advanced features such as remote logging and trend monitoring make the Fluke 376FC a valuable tool for professional use in demanding environments.
