10 Best Clamp Multimeters 2026 in the United States

The Fluke 378FC is a reliable clamp multimeter designed for electricians and professionals who need accurate current and voltage measurements without direct contact with live wires. It uses FieldSense technology to safely measure voltage and current, which speeds up testing and reduces risk. It supports up to 1000A AC/DC current and can measure very low voltages starting from 0.1 millivolts, making it versatile for various electrical tasks.

The meter includes a clear display and a power quality indicator that helps detect electrical faults, adding value for diagnosing equipment issues. The clamp jaw opening is large enough for standard cables, and the wireless feature allows data to be sent to your smartphone for easier monitoring. It meets important safety standards like CE and FCC, ensuring safe operation in demanding environments.

The device is a bit heavier at over 3 pounds, which might be less convenient for extended handheld use. The wireless functionality depends on the user having compatible devices and apps to fully benefit from it. This meter is well-suited for professionals needing precise, safe, and efficient measurements, especially in industrial or commercial settings.

The Fluke 902 FC HVAC True-RMS Clamp Meter is designed with HVAC technicians in mind, offering specialized features that make it a strong tool for that category. It supports DC current measurements up to 200 amps, which is especially useful for tasks like measuring flame rods. Its extended resistance range up to 60k ohms allows you to test thermistors, which is helpful in HVAC work. The meter can also capture flue gas temperature, adding to its versatility. One standout feature is its True-RMS capability, ensuring accurate readings even on tricky, non-linear electrical signals. The meter connects wirelessly via Bluetooth to your phone, which helps save time and enhances safety by letting you monitor readings remotely. It is battery powered with two AA batteries and is relatively lightweight and portable.

The Fluke brand is well-known for reliability, making this clamp meter particularly suitable for HVAC professionals needing precise current, resistance, and temperature measurements in their fieldwork. Its wireless capability and True-RMS measurements provide a modern, convenient edge.

Users seeking a clamp meter for broader electrical work beyond HVAC might find its specialized functions less useful. Additionally, for general electrical use or heavy industrial testing, some specific features may not fully meet all requirements.

The Fluke 376FC AC/DC Clamp Meter is a strong choice for industrial and commercial electricians needing precise and versatile current measurements. It can measure both AC and DC currents up to 1000A using its flexible iFlex probe, which is useful for accessing tight or awkward spaces. The meter includes a VFD low pass filter that helps provide more accurate readings when working with variable frequency drives, a common challenge in industrial settings.

One of its standout features is Bluetooth connectivity, allowing you to send measurements wirelessly to your smartphone. This is handy for monitoring values remotely, reducing the need for extra protective gear because you can read data safely from a distance. It also supports logging measurements over time and sharing reports or live video calls from the field, enhancing troubleshooting and collaboration. The display is digital and clear, and the device is powered by two AA batteries, making it lightweight and portable.

Fluke products generally meet high safety standards suitable for industrial environments. If you often work with complex electrical systems and value remote monitoring and data logging, this meter fits well. Those who require very large jaw capacity or detailed safety certifications should verify those aspects before purchase.
