The new Fluke-437-II helps 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. Below you will find brief descriptions of these new features.

The Fluke 437 Series II Power Quality and Energy Analyzer is designed specifically for the defense and avionics industries. Equipped with all the functionalities of the 435 II including PowerWave, Power Inverter Efficiency and an Energy Loss Calculator, the 437 II goes one step further by measuring up to 400 Hz. The ability to measure at a higher frequency is necessary for those working in submarines, aircrafts, and other transport applications.

Fluke's patented Unified Power Measurement system (UPM) provides the most comprehensive view of power available, measuring:

- Parameters of Classical Power (Steinmetz 1897) and IEEE 1459-2000 Power
- Detailed Loss Analysis
- Unbalance Analysis
