10 Best The Fluke Multimeter 2026 in the United States

The Fluke 789 ProcessMeter is a robust and versatile tool designed for industrial and scientific use. One of its significant strengths is its accuracy and wide range of measurement capabilities. It can measure and source 4-20 mA signals, making it particularly useful for professionals working in process control. The built-in 24V loop power supply is another excellent feature, allowing users to power and test process instruments directly without additional equipment.

This ProcessMeter also includes standard digital multimeter (DMM) capabilities, which adds to its versatility. The accuracy is reliable, and the device offers manual and automatic stepping on mA output, which can enhance efficiency during testing and calibration tasks. The selectable 250-Ohm Hart resistor and quick span check buttons further facilitate ease of use in various scenarios. Safety is a top priority with the Fluke 789. It offers 1000V overload protection on voltage, ohms, and frequency measurements, and 150V overload protection on current measurements. These are significant safeguards, especially in industrial settings. Moreover, the device is backed by a robust 440 mA 1000V fuse.

The display is another notable feature; it is a large dual screen with enhanced backlight, making it easy to read even in low-light conditions. The backlight has two brightness settings to suit different environments. However, there are a few drawbacks to consider. The battery life, while decent, may require frequent changes if you're sourcing current often, as it runs about 12 hours typical when sourcing 12 mA. Additionally, the device is relatively heavy at 1.34 pounds and might be cumbersome for prolonged handheld use. Despite these minor downsides, the Fluke 789 ProcessMeter stands out as a highly reliable and feature-rich tool, ideal for professionals in process control and industrial settings.

The Fluke 378FC AC/DC TRMS Non-Contact Voltage Wireless Clamp is a robust and versatile multimeter. One of its standout features is FieldSense technology, allowing for faster and safer testing without the need to touch live wires. This enhances both user safety and efficiency. The clamp jaw design is convenient for measuring voltage and current, and the iFlex feature extends its measurement range, making it suitable for various applications, including complex electrical systems.

It also includes a Power Quality indicator, which helps diagnose whether issues stem from equipment or power lines, adding a layer of diagnostic capability that's valuable in troubleshooting scenarios. The device is well-regarded for its accuracy, essential for reliable readings in professional settings. Its wireless capability makes it easy to record and share data, reducing manual logging time.

However, the weight of 3.28 pounds might be a slight drawback for users who need to carry it around frequently, and the size might be cumbersome in tight spaces. The display quality, while sufficient, could benefit from enhanced visibility in low-light conditions. Safety ratings are robust, ensuring compliance with industry standards, and the inclusion of two AA batteries provides convenience. This multimeter is well-suited for professional electricians and technicians who require precise, safe, and efficient tools for complex electrical testing and diagnostics.

The Fluke 376FC is a solid choice for industrial and commercial electricians who need to measure AC and DC current safely and accurately. It comes with an 18-inch or 36-inch iFlex flexible current probe, which lets you access hard-to-reach places easily and measure currents up to 1000A. Its accuracy is reliable for professional use, and the VFD low pass filter helps get precise readings even around variable frequency drives, which can be tricky with other meters. The large, easy-to-read display is complemented by Bluetooth connectivity, allowing you to send measurements directly to your smartphone. This is a handy feature for logging data remotely or sharing results in real time, reducing the need to be physically close to the electrical panel—boosting safety and convenience.

The meter is battery-powered and lightweight, making it comfortable to carry on the job. It also supports inrush current measurements, useful for diagnosing motor startups and other transient events. While the meter covers most needs for industrial electricians, it might be more advanced (and pricier) than necessary for casual or home users. Also, because it relies on Bluetooth and smartphone integration, users should be comfortable with that tech to get the most benefit.

The device is well-built with good safety ratings typical of Fluke products, ensuring it can handle tough job site conditions. To summarize, the Fluke 376FC offers versatility, accuracy, and a rich feature set that suits professionals looking for reliable measurements and smart connectivity on the job.
