Power Analyzer

Measure, Analyze, and Optimize Electrical Power

At Duncan Instruments Canada, we offer one of the most comprehensive selections of power analyzers in the country. Whether you're measuring real power (W), energy consumption (kWh), or analyzing harmonics (THD), our multi-function analyzers deliver accurate, reliable results.

These devices can measure:

  • Direct and alternating current (DC/AC)
  • Voltage (DC/AC)
  • Apparent (VA), reactive (VAR), and true power (W)
  • Power factor (PF) and phase rotation
  • Harmonics (THD) and frequency (Hz)

Power analyzers calculate True RMS values by analyzing the full waveform across an AC cycle—ensuring accurate readings even under complex loads. They acquire data using voltage dividers and current transformers, then compute energy flow using precise mathematical models.

Where available, our pricing is automatically compared against major Canadian competitors to help you get the best deal—updated several times daily.
