Description

Fluke 381 True RMS AC/DC Clamp Meter with Detachable Wireless Display

The Fluke 381 True RMS AC/DC Clamp Meter is an advanced professional electrical measuring instrument designed to deliver maximum flexibility, safety, and accuracy for electricians, industrial maintenance engineers, utility technicians, HVAC professionals, facility managers, electrical contractors, automation engineers, renewable energy specialists, and field service technicians. Combining True RMS measurement technology, 1000A AC/DC current measurement, a unique detachable wireless display, and compatibility with the Fluke iFlex® Flexible Current Probe, the Fluke 381 is engineered to simplify electrical testing in challenging environments while enhancing operator safety.

Industrial electrical systems are becoming increasingly complex, with densely populated control panels, high-current conductors, variable frequency drives (VFDs), programmable logic controllers (PLCs), switchgear, transformers, renewable energy systems, and automation equipment requiring precise diagnostic tools. Traditional clamp meters often force technicians into awkward positions when measuring energized conductors inside crowded electrical cabinets. The Fluke 381 overcomes these limitations through its innovative wireless detachable display, allowing users to separate the display from the clamp meter and view live readings from a safe and convenient distance.

The removable wireless display provides exceptional flexibility when working inside large electrical panels, motor control centers, industrial switchgear, overhead conductors, confined equipment spaces, or hazardous environments. One technician can safely position the clamp around the conductor while observing measurement results remotely, reducing physical strain and minimizing exposure to energized electrical equipment. This feature is especially valuable for applications where direct line-of-sight to the display is difficult or where maintaining a safer working distance is preferred.

The Fluke 381 measures AC and DC current up to 1000 Amps using its high-performance clamp jaw, enabling safe, non-contact current measurements without disconnecting energized conductors. This allows maintenance professionals to troubleshoot electrical systems while minimizing production downtime and reducing maintenance risks. The instrument is ideal for monitoring industrial motors, transformers, generators, compressors, pumps, HVAC equipment, renewable energy installations, battery systems, and electrical distribution networks.

To ensure dependable performance in modern electrical environments, the Fluke 381 incorporates True RMS measurement technology. Many industrial systems contain non-linear electrical loads generated by VFDs, inverters, UPS systems, LED lighting, electronic motor controls, and switch-mode power supplies. Conventional averaging meters may provide misleading readings under these conditions. True RMS technology delivers accurate measurements regardless of waveform distortion, providing confidence during troubleshooting and preventive maintenance.

The Fluke 381 also measures AC and DC voltage up to 1000V, allowing technicians to inspect power distribution systems, verify electrical supplies, troubleshoot control circuits, commission equipment, and perform routine maintenance across residential, commercial, and industrial electrical installations.

Additional multimeter functions include resistance, continuity, frequency, capacitance, Min/Max recording, and Inrush Current measurement, enabling comprehensive diagnostics with a single instrument. Inrush current measurement is particularly useful when evaluating motor startup performance, transformer energization, compressor operation, and circuit breaker selection.

A major advantage of the Fluke 381 is its compatibility with the Fluke iFlex® Flexible Current Probe (sold separately or included in selected kits). The iFlex probe extends current measurement capability while allowing access to oversized conductors, tightly bundled cables, and busbars that may not fit inside conventional clamp jaws. This added flexibility significantly expands the instrument’s application range in industrial facilities, utility substations, renewable energy installations, and manufacturing plants.

The Fluke 381 features a large backlit LCD display that remains highly visible in electrical rooms, substations, manufacturing facilities, outdoor service locations, and low-light maintenance environments. The detachable wireless display allows technicians to monitor measurements remotely while maintaining a comfortable viewing angle.

The clamp meter includes valuable productivity features such as Data Hold, Auto Ranging, Min/Max recording, Automatic Power-Off, and low battery indication. These features improve measurement efficiency while extending battery life during daily field operation.

Built with Fluke’s renowned rugged construction, the Fluke 381 is designed to withstand demanding industrial environments including manufacturing plants, oil and gas facilities, mining operations, utilities, commercial buildings, transportation infrastructure, renewable energy sites, chemical processing plants, and heavy industrial maintenance operations.

Safety is one of the defining characteristics of Fluke electrical instruments. The Fluke 381 complies with CAT IV 600V and CAT III 1000V safety standards, providing qualified technicians with confidence when working on service entrances, industrial power distribution equipment, permanently installed electrical systems, and commercial electrical infrastructure.
