Understanding Precision Power Analyzers: A Guide for Engineers and Metrologists

When accuracy and reliability matter, a precision power analyzer becomes more than a convenience—it becomes a necessity. Engineers, metrologists, and test labs rely on these instruments to evaluate power quality, efficiency, and system behavior in everything from power supplies to advanced industrial applications.

At Duncan Instruments, we partner with Infratek AG of Switzerland, a family-owned company known for designing and manufacturing exceptionally accurate power analyzers tailored to real-world needs.

Why Precision Matters

In many applications, regulatory compliance, product performance, and safety all depend on power measurements you can trust. Low-end instruments may suffice for general diagnostics, but when you're calibrating equipment, validating energy efficiency, or certifying systems, small measurement errors can lead to costly outcomes.

This is where a properly engineered analyzer—offering tight accuracy specs, low phase shift, and flexible current/voltage inputs—makes all the difference.

Key Features to Look For

Modern precision power analyzers like the Infratek 108A series offer:

  • True RMS measurements for voltage and current

  • Simultaneous multi-phase analysis

  • Support for external current transducers and Rogowski coils

  • Adjustable bandwidth and sampling for different environments

  • Configurable accuracy options (±0.1% Basic or ±0.02% Enhanced)

These capabilities allow you to match your instrument to the task—whether it's utility metering verification, R&D, or compliance testing.

Designed for Professionals

At Duncan Instruments, we’ve worked with calibration labs, control system developers, and power engineers who need precision—not just specs on paper, but consistent results under real-world conditions. That’s why we stand behind Infratek’s 108A series.
