Description

Fluke 373 True RMS AC Clamp Meter for Commercial and Industrial Applications

The Fluke 373 True RMS AC Clamp Meter is a professional-grade electrical testing instrument designed to provide accurate, reliable, and safe electrical measurements for commercial, industrial, and maintenance applications. Engineered for electricians, industrial maintenance engineers, facility managers, HVAC technicians, electrical contractors, utility personnel, automation specialists, and field service professionals, the Fluke 373 combines True RMS measurement technology, 600 Amp AC current capability, and comprehensive voltage testing functions in a compact, rugged, and easy-to-use design.

Electrical systems in modern industrial and commercial facilities often include Variable Frequency Drives (VFDs), programmable logic controllers (PLCs), motor control centers, switch-mode power supplies, UPS systems, LED lighting, and electronic automation equipment. These systems frequently generate non-linear electrical waveforms that conventional averaging meters cannot accurately measure. The Fluke 373 addresses this challenge with True RMS technology, ensuring dependable current and voltage readings even when waveform distortion is present.

The Fluke 373 measures AC current up to 600 Amps using a non-contact clamp jaw that allows technicians to monitor energized conductors without disconnecting wiring or interrupting equipment operation. This significantly improves workplace safety while reducing maintenance time and minimizing production downtime during electrical inspections.

Designed specifically for professional maintenance work, the Fluke 373 enables technicians to inspect electrical feeders, transformers, switchboards, distribution panels, motor control centers, HVAC systems, manufacturing equipment, generators, compressors, and commercial electrical installations with confidence. The non-contact current measurement method eliminates the need to break electrical circuits, making routine maintenance faster, safer, and more efficient.

In addition to AC current measurement, the Fluke 373 provides AC and DC voltage measurement using the supplied test leads. This functionality enables technicians to verify incoming electrical supplies, inspect industrial machinery, troubleshoot electrical distribution systems, commission new installations, and evaluate electrical equipment throughout manufacturing facilities, commercial buildings, hospitals, educational institutions, and utility infrastructure.

The Fluke 373 also supports resistance measurement and continuity testing, allowing electricians to quickly diagnose wiring faults, inspect electrical components, verify circuit integrity, test switches, relays, motors, transformers, heating elements, and electrical connections. Audible continuity testing accelerates cable verification and installation inspections while reducing troubleshooting time.

One of the key advantages of the Fluke 373 is its large jaw opening, designed to accommodate oversized conductors commonly found in industrial electrical installations. Whether working with heavy motor feeders, transformer cables, switchgear, or commercial power distribution systems, technicians benefit from convenient conductor access without compromising measurement accuracy.

The large backlit LCD display offers excellent visibility in indoor electrical rooms, manufacturing plants, outdoor utility installations, construction sites, and low-light maintenance environments. High-contrast digital readings improve measurement confidence while reducing eye strain during extended inspection and troubleshooting activities.

The Fluke 373 is constructed using durable industrial-grade materials designed to withstand demanding field environments. Its rugged housing protects the instrument from accidental impacts, vibration, and daily professional use commonly encountered in industrial manufacturing, oil and gas facilities, utilities, renewable energy installations, mining operations, commercial buildings, and infrastructure maintenance projects. Despite its robust construction, the clamp meter remains lightweight and ergonomically balanced for comfortable one-handed operation throughout long working days.

Safety is one of the defining characteristics of every Fluke instrument. The Fluke 373 complies with CAT III 600V and CAT IV 300V safety standards, making it suitable for measurements on industrial distribution systems, commercial electrical installations, branch circuits, utility service entrances, and permanently installed electrical equipment. These internationally recognized safety ratings provide confidence while performing measurements on energized electrical systems according to accepted electrical safety procedures.

To improve technician productivity, the Fluke 373 includes useful features such as Data Hold, allowing displayed measurements to be frozen for documentation, and Automatic Power-Off, which conserves battery life during periods of inactivity. These features maximize operational efficiency while minimizing maintenance requirements.

The Fluke 373 is an ideal instrument for preventive maintenance programs, electrical inspections, commissioning, fault diagnosis, energy audits, equipment verification, and routine maintenance activities across virtually every industrial sector.
