Power Analyzers — Buy & Sell Used Power Analyzers

A power analyzer is chosen on channel count, bandwidth, basic accuracy class, and current-input range. Channels (often called elements) determine whether you can measure single-phase, three-phase, or multi-input systems simultaneously — and you need enough of them to capture every leg at once. Bandwidth matters most for inverter, PWM, and switching work, where high-frequency content carries real power. Accuracy class defines how trustworthy your efficiency and loss numbers are, and the current input arrangement (direct shunts vs external current sensors or CTs) sets your usable current range.

Used value follows installed input elements, current-measurement accessories, and analysis options. Yokogawa's WT series, Hioki's PW line, and Keysight power analyzers license features like harmonic analysis, motor/mechanical inputs, and standardized compliance tests, and the external current sensors are expensive in their own right — so a unit that includes matching sensors is worth more. Because this is a precision, accuracy-class instrument, a current and traceable calibration certificate materially affects both usability and price. List the installed elements and sensors when you request a quote.

Refurbished power analyzers typically save 40-70% off list, and a calibrated unit performs to its accuracy class just as a new one does. Yokogawa WT and Hioki PW families hold value especially well for precision power and efficiency testing. Whether you're sourcing a unit or retiring one, send us the model, its installed elements, and any current sensors, and we'll quote within one business day.
