Description

The Fluke 434 Series II Three Phase Power Quality Analyzer is a professional-grade diagnostic instrument designed to deliver comprehensive power quality measurements and advanced energy analysis for industrial, commercial, and utility electrical systems. Combining rugged field durability with precise measurement technology, the 434 Series II captures a wide array of electrical parameters including voltage, current, power, energy, frequency, power factor, harmonics, interharmonics, flicker, transient events, and system unbalance across three phases.

With its high-resolution graphical display and intuitive interface, setup and operation are straightforward even in complex installations. The analyzer’s fast sampling rate and large internal memory enable continuous recording of power quality data along with event logging, ensuring that both steady-state conditions and transient disturbances are captured for thorough analysis. Multiple trigger and logging modes help technicians focus on specific issues such as sags, swells, transients, and harmonic distortion.

Designed for demanding field environments, the Fluke 434 Series II features rugged construction, robust safety ratings, and easy-to-connect flexible current probes or clamps for safe operation up to 1000 V. After data collection, results can be downloaded to a PC for in-depth evaluation using companion software, which offers powerful visualization tools, customizable reporting, trend analysis, and automated compliance assessment against international power quality standards.

Ideal for power quality audits, troubleshooting electrical problems, verifying compliance, and optimizing energy efficiency, the Fluke 434 Series II delivers accurate, reliable data to help professionals diagnose complex issues and improve electrical system performance.
