The Fluke 437-II Energy and Power Quality Analyzer delivers three-phase power diagnostics across 50 Hz, 60 Hz, and 400 Hz systems. Purpose-built for aviation, military, and marine environments, it locates, predicts, prevents, and troubleshoots power quality issues with Class-A compliance to IEC 61000-4-30. The instrument measures all three phases and neutral with 0.01 V resolution, capturing fast RMS data including half-cycle waveforms and transient events up to 200 kHz across all phases simultaneously at potentials to 6 kV.
