Description

Fluke 325 True RMS Clamp Meter with Temperature and Capacitance Measurement

The Fluke 325 True RMS Clamp Meter is a versatile, professional-grade electrical measuring instrument designed to meet the needs of electricians, HVAC technicians, industrial maintenance engineers, electrical contractors, facility managers, refrigeration specialists, utility technicians, and field service professionals. Combining True RMS measurement technology, AC/DC current measurement, temperature measurement, capacitance testing, and comprehensive digital multimeter functions, the Fluke 325 is an ideal solution for troubleshooting, preventive maintenance, installation, commissioning, and diagnostics across residential, commercial, and industrial electrical systems.

As electrical and HVAC systems continue to evolve with inverter-driven compressors, variable frequency drives (VFDs), electronically commutated motors (ECMs), programmable controllers, switch-mode power supplies, renewable energy equipment, and advanced automation systems, technicians require instruments capable of delivering accurate measurements under real operating conditions. Conventional averaging meters often struggle to measure distorted electrical waveforms accurately. The Fluke 325 incorporates True RMS technology, ensuring reliable readings for both sinusoidal and non-linear signals generated by modern electrical equipment.

The Fluke 325 measures AC and DC current up to 400 Amps using its integrated non-contact clamp jaw. This allows technicians to safely measure energized conductors without disconnecting wiring or interrupting equipment operation. Non-contact current measurement significantly improves workplace safety while reducing maintenance time and minimizing production downtime. The clamp meter is well suited for monitoring motors, compressors, transformers, HVAC equipment, electrical feeders, pumps, generators, switchboards, and industrial distribution systems.

In addition to current measurement, the Fluke 325 provides accurate AC and DC voltage measurement using the supplied test leads. This enables professionals to inspect electrical panels, verify power supplies, troubleshoot control circuits, commission new equipment, and diagnose faults in commercial and industrial electrical installations. Voltage testing is essential when servicing motor control centers, distribution boards, renewable energy systems, refrigeration equipment, and building electrical infrastructure.

One of the key advantages of the Fluke 325 is its integrated temperature measurement capability. When used with a compatible thermocouple, technicians can monitor the temperature of motors, transformers, HVAC ducts, condenser and evaporator coils, compressors, electrical panels, bearings, and industrial machinery. Temperature monitoring helps identify overheating components, verify system performance, and support predictive maintenance programs.

The Fluke 325 also features capacitance measurement, making it particularly valuable for HVAC and refrigeration technicians who regularly test motor start capacitors, run capacitors, and other capacitive components. Accurate capacitance measurement simplifies troubleshooting of compressors, blower motors, condenser fan motors, and refrigeration systems, reducing equipment downtime and improving service efficiency.

Additional measurement capabilities include resistance, continuity, and frequency testing, allowing users to inspect wiring, relays, switches, motors, transformers, sensors, heating elements, electrical connections, and control circuits. Audible continuity testing provides quick verification of wiring integrity and circuit paths during installation and maintenance work.

The large backlit LCD display offers excellent readability in electrical rooms, manufacturing plants, rooftop HVAC installations, commercial buildings, substations, and other low-light maintenance environments. High-contrast readings reduce eye strain and improve measurement accuracy during extended service operations.

Designed with a compact ergonomic clamp jaw, the Fluke 325 provides convenient access to conductors inside electrical panels, motor control centers, HVAC units, switchboards, and industrial control cabinets. Its lightweight construction supports comfortable one-handed operation, making it suitable for prolonged daily use in demanding field environments.

Built with Fluke’s renowned rugged construction, the Fluke 325 is capable of withstanding the harsh conditions commonly encountered in manufacturing facilities, industrial plants, oil and gas installations, construction sites, commercial buildings, hospitals, educational institutions, utilities, and maintenance workshops. Its impact-resistant housing protects internal electronics while ensuring long service life.

Safety remains one of Fluke’s highest priorities. The Fluke 325 complies with CAT III 600V and CAT IV 300V safety standards, allowing qualified technicians to safely perform measurements on branch circuits, distribution panels, industrial equipment, permanently installed electrical systems, and commercial electrical infrastructure. These internationally recognized safety ratings provide confidence while working around energized equipment.

Additional productivity features include Data Hold, Backlight, Automatic Power-Off, and Auto Ranging, enabling technicians to perform measurements more efficiently while extending battery life during everyday operation.
