Fluke 435-II Power Quality Analyzer with 4 Flexible Current Probes

Fluke 435-II Power Quality Analyzer

The Fluke 435-II is the industry’s most advanced handheld power quality analyzer, designed for professionals who demand precision and reliability in electrical system troubleshooting, commissioning, and maintenance. This Class-A compliant instrument (per IEC 61000-4-30) combines the functionality of a power analyzer, oscilloscope, recorder, and data logger into one compact, rugged device. With the ability to measure all three phases and neutral simultaneously, the 435-II provides a complete picture of your electrical system’s health.

Key Features & Highlights

• Class-A Compliance: Meets the stringent international IEC 61000-4-30 Class-A standard for accurate and repeatable power quality measurements.
• Energy Loss Calculator: Quantifies active and reactive power losses, unbalance, and harmonic power to pinpoint true system energy losses in dollars or local currency.
• Power Inverter Efficiency: Measures AC output and DC input power simultaneously using optional DC clamps for power electronics systems.
• PowerWave Data Capture: Captures fast RMS data, half-cycle, and waveforms to characterize electrical system dynamics such as generator start-ups and UPS switching.
• Waveform Capture: Records 100/120 cycles (50/60 Hz) of each detected event in all modes without setup.
• Automatic Transient Mode: Captures 200 kHz waveform data on all phases simultaneously up to 6 kV.
