HG-904A Dual Channel Machinery Frequency Spectrum Analyzer for Vibration Detection

The HG-904A Dual Channel Machinery Frequency Spectrum Analyzer is designed for dynamic balancing and vibration detection. Imbalance is one of the main causes of machine vibration, accounting for approximately 50% of all faults. This analyzer provides on-site balancing capabilities by measuring vibration intensity, diagnosing causes through frequency spectrum analysis, and calculating imbalance weight and location.
