10 Best The Fluke Multimeter 2026 in the United States

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.

The Fluke 28IIEX/ETL Intrinsically Safe True-Rms Digital Multimeter is a robust tool designed for use in hazardous environments such as oil refineries and mining operations. Its intrinsic safety features ensure it can be used in explosive atmospheres without risk, making it highly suitable for professionals working in these fields. The True-RMS capability of the multimeter ensures accurate readings regardless of whether the current or voltage waveform is sinusoidal or nonsinusoidal, which is crucial for technical precision in various scenarios.

It measures a wide range of parameters, including voltage, current, conductance, duty cycle, capacitance, frequency, and temperature, and can perform resistance, continuity, and diode tests, making it a versatile tool for a broad range of applications. The device includes a low-pass filter to block unwanted voltages for accurate measurements, especially useful when working with inverters and variable-frequency motor drives. The LCD display provides clear readings, although it may not be backlit, which could be a drawback in low-light environments.

Safety-wise, it has impressive ratings, including IP67, which denotes it is dust-tight and can withstand immersion in water up to a meter deep. It is also certified for use in environments with explosive gases and conductive dust, offering peace of mind in industrial settings. The additional certification for Category III installations up to 1000V and Category IV installations up to 600V indicates its suitability for high-voltage professional use. Weighing 2.95 pounds, it’s relatively heavy, which may affect portability for some users. With a decent battery life and a robust build, it is durable and reliable for rigorous industrial use.

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.
