Fluke 435-II Three-Phase Power Quality & Energy Analyzer

Power Quality is a measure of how well a system supports reliable operation of its loads. A power disturbance or event can involve voltage, current, or frequency.

The new Fluke 430 Series II Three-Phase Power Quality and Energy Analyzers offer the best in power quality analysis and introduce, for the first time ever, the ability to monetarily quantify energy losses.


The new Fluke 435 II models help locate, predict, prevent, and troubleshoot power quality problems in three-phase and single-phase power distribution systems. Additionally, these models feature revolutionary power quality and energy measurement functions that help facilities reduce electrical power consumption, and improve the performance and lifespan of electro-mechanical equipment.
