World-class Accuracy, Stability, and Versatility

Measuring true power is more than multiplying voltage and current. Advances in complex power electronics and energy efficiency create measurement challenges that can confound even the most experienced engineers.

Unlike data acquisition and oscilloscope-based power measurement tools, power analyzers are purpose-built to guarantee measurement accuracy when testing devices that generate, transform, or consume electricity.

Yokogawa, the world's leading supplier of electrical power analyzers, provides solutions for testing power electronics, inverters, motors and drives, lighting, home appliances, office equipment, power supplies, industrial machinery and more.
