Fluke 179 True RMS Digital Multimeter with Temperature Measurement Capability
The Fluke 179 True RMS Digital Multimeter is a premium professional handheld measuring instrument designed for electricians, industrial maintenance engineers, HVAC technicians, automation specialists, field service professionals, utility personnel, and process control engineers who require exceptional measurement accuracy and dependable performance. Featuring True RMS technology, integrated temperature measurement capability, and comprehensive electrical testing functions, the Fluke 179 is one of the most versatile digital multimeters available for industrial, commercial, and field service applications.
Modern electrical and industrial systems integrate sophisticated electronic controls, automation equipment, variable frequency drives (VFDs), programmable logic controllers (PLCs), intelligent building management systems, renewable energy installations, and electronically controlled motors. These systems often generate distorted electrical waveforms that cannot be accurately measured using conventional average-responding multimeters. The Fluke 179 utilizes advanced True RMS technology to provide precise readings on both sinusoidal and non-linear waveforms, ensuring reliable diagnostics in today’s complex electrical environments.
One of the key features that distinguishes the Fluke 179 from other professional multimeters is its built-in temperature measurement capability. When used with the supplied or compatible K-type thermocouple, technicians can accurately measure temperatures of electrical panels, motors, transformers, bearings, compressors, HVAC equipment, refrigeration systems, heating elements, process equipment, boilers, switchgear, and industrial machinery. Temperature monitoring plays a vital role in predictive maintenance, helping maintenance teams detect overheating components before failures occur.
The Fluke 179 features a large 6000-count digital LCD display with an integrated backlight that provides excellent visibility in virtually any working environment. Whether troubleshooting inside electrical panels, control cabinets, manufacturing plants, utility facilities, commercial buildings, or mechanical rooms, technicians benefit from clear, stable, and easy-to-read measurement values that improve productivity and reduce diagnostic errors.
Built for demanding industrial environments, the Fluke 179 features a rugged ergonomic housing capable of withstanding daily professional use. Its durable construction protects the instrument against accidental impacts and harsh working conditions while maintaining dependable performance throughout years of service.
Safety is one of the defining characteristics of the Fluke 179. The instrument complies with CAT III 1000V and CAT IV 600V safety ratings, making it suitable for measurements on industrial distribution systems, commercial electrical installations, feeders, service entrances, switchgear, motor control centers, permanently installed equipment, and utility power systems. These industry-leading safety classifications provide confidence when working on energized electrical equipment while following established electrical safety procedures.
The Fluke 179 supports a comprehensive range of electrical measurement functions that allow professionals to perform virtually every routine diagnostic task using a single instrument. It accurately measures AC voltage, DC voltage, AC current, DC current, resistance, capacitance, frequency, continuity, diode characteristics, and temperature. This versatility reduces the need for multiple instruments while increasing maintenance efficiency.
Accurate AC and DC voltage measurement allows technicians to inspect electrical installations, verify incoming power supplies, commission machinery, troubleshoot electrical faults, and confirm proper equipment operation. Reliable voltage measurements are essential for maintaining safe and efficient electrical systems.
Current measurement functions enable maintenance personnel to monitor motor loads, analyze equipment performance, verify electrical consumption, detect overloaded circuits, and identify abnormal operating conditions before equipment damage occurs. This capability supports preventive maintenance programs and reduces unexpected downtime.
Resistance measurement assists in evaluating electrical wiring, motors, transformers, relays, switches, sensors, heating elements, and electrical connections. Detecting abnormal resistance values early allows technicians to identify deteriorating components before complete failure occurs.
Capacitance measurement simplifies testing of motor capacitors, HVAC systems, industrial controllers, electronic circuits, and power conditioning equipment. Accurate capacitor testing accelerates maintenance activities and improves diagnostic efficiency.
Frequency measurement provides valuable information when servicing generators, UPS systems, VFDs, industrial automation equipment, electronic power supplies, and renewable energy installations. Accurate frequency verification ensures equipment operates within design specifications.
The audible continuity function enables rapid verification of electrical continuity without requiring constant observation of the display. This feature improves efficiency during cable tracing, installation verification, switch testing, and wiring inspections.
The diode testing function supports evaluation of semiconductor devices used in automation controls, industrial electronics, communication equipment, PLC systems, and electronic control boards, making the Fluke 179 suitable for both electrical and electronic troubleshooting.
Temperature measurement adds another valuable dimension to equipment diagnostics. By monitoring thermal conditions alongside electrical parameters, technicians can detect overheating bearings, overloaded motors, failing transformers, hot electrical connections, compressor problems, and HVAC system inefficiencies before they result in costly failures.
The Fluke 179 offers both automatic and manual ranging, allowing users to select the most appropriate operating mode for each application. Auto-ranging improves speed during routine maintenance, while manual ranging offers greater control during precision measurements.
Additional productivity features include Data Hold, which freezes displayed measurements for easy recording, and Min/Max recording, which captures fluctuating electrical values during intermittent faults or changing load conditions. These features are especially useful for preventive maintenance and advanced troubleshooting.
