Fluke 353 2000A AC/DC True RMS Clamp Meter for High Current Industrial Applications
The Fluke 353 2000A AC/DC True RMS Clamp Meter is a heavy-duty professional electrical measuring instrument engineered specifically for high-current industrial applications. Designed for industrial maintenance engineers, utility technicians, power distribution specialists, electrical contractors, renewable energy professionals, manufacturing engineers, mining personnel, oil and gas technicians, and field service engineers, the Fluke 353 delivers exceptional accuracy, safety, and durability when measuring large electrical currents in demanding environments.
High-current electrical systems found in industrial manufacturing plants, utility substations, heavy machinery, generators, transformers, switchgear, motor control centers, renewable energy facilities, and power distribution networks require measuring instruments capable of handling substantial electrical loads while maintaining precision. The Fluke 353 has been purpose-built for these applications, offering AC/DC current measurement up to 2000 Amps, advanced True RMS technology, and comprehensive multimeter functions that enable professionals to perform accurate diagnostics with confidence.
Unlike conventional clamp meters intended for standard electrical maintenance, the Fluke 353 is optimized for measuring large conductors and high-current circuits commonly found in industrial installations. Its oversized clamp jaw easily accommodates large-diameter cables and busbars, allowing technicians to safely perform current measurements without disconnecting energized conductors or interrupting equipment operation. This non-contact testing method improves workplace safety, minimizes production downtime, and enhances maintenance efficiency.
The Fluke 353 measures both AC and DC current up to 2000 Amps, making it suitable for inspecting industrial motors, generators, transformers, battery banks, DC power systems, renewable energy installations, electric vehicle charging infrastructure, welding equipment, mining machinery, large compressors, industrial pumps, and heavy manufacturing equipment. The ability to measure both alternating and direct current provides exceptional versatility across modern industrial environments.
To ensure measurement accuracy under real operating conditions, the Fluke 353 incorporates True RMS technology. Modern electrical systems frequently include Variable Frequency Drives (VFDs), programmable logic controllers (PLCs), switch-mode power supplies, inverters, UPS systems, and electronic motor controls that generate distorted electrical waveforms. True RMS measurement ensures dependable readings regardless of waveform shape, enabling technicians to diagnose electrical systems accurately.
In addition to high-current measurement, the Fluke 353 functions as a professional digital multimeter capable of measuring AC/DC voltage up to 1000V, resistance, frequency, and continuity. These functions allow technicians to troubleshoot electrical distribution systems, commission industrial equipment, inspect renewable energy installations, evaluate power supplies, verify wiring integrity, and diagnose faults using a single instrument.
Voltage measurement supports inspection of industrial switchgear, motor control centers, utility equipment, battery storage systems, automation panels, transformers, renewable energy systems, and commercial electrical infrastructure. Resistance testing allows verification of motors, transformers, electrical connections, relays, switches, heating elements, and wiring, while continuity testing quickly identifies open circuits and poor electrical connections.
The Fluke 353 features a large backlit LCD display designed for excellent readability in electrical substations, manufacturing plants, utility facilities, outdoor installations, mining sites, renewable energy projects, and low-light industrial environments. High-contrast digital readings reduce operator fatigue and improve measurement confidence during extended maintenance operations.
Its oversized clamp jaw is specifically designed to accommodate large conductors, multiple cables, and busbars commonly encountered in high-current applications. This expanded jaw capacity allows technicians to work efficiently on industrial electrical equipment where smaller clamp meters cannot provide adequate clearance.
The instrument includes practical productivity features such as Data Hold, Min/Max recording, Peak measurement, Auto Ranging, and Automatic Power-Off. These capabilities help technicians capture transient events, monitor fluctuating electrical loads, simplify operation, and extend battery life during field service.
Built for demanding industrial environments, the Fluke 353 incorporates rugged impact-resistant construction capable of withstanding harsh conditions encountered in manufacturing facilities, steel plants, mining operations, utilities, petrochemical plants, marine applications, renewable energy facilities, transportation infrastructure, and heavy industrial maintenance. The durable housing protects internal electronics while maintaining excellent portability for field technicians.
Safety is one of Fluke’s defining characteristics. The Fluke 353 complies with CAT IV 600V and CAT III 1000V safety standards, making it suitable for service entrances, industrial distribution systems, utility infrastructure, permanently installed electrical equipment, commercial installations, and branch circuits. These internationally recognized safety ratings provide technicians with confidence when working around energized high-current electrical systems.
