FLUKE 434 Series II Energy Analyser

The FLUKE 434 help you locate, predict, prevent, and troubleshoot power quality problems in three-phase and single-phase power distribution systems.  Help your facilities reduce electrical power consumption, and improve the performance and lifespan of electro-mechanical equipment.


FLUKE 434 Unified Power Measurement

Determine how much power is being wasted, and calculate exactly what the extra consumption costs.  FLUKE’s patented Unified Power Measurement System provides the most comprehensive view of power available, measuring:

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

These UPM calculations are used to quantify the fiscal cost of energy loss caused by power quality issues. The calculations are computed, along with other facility-specific information by an Energy Loss Calculator that ultimately determines how much money a facility loses due to wasted energy.


FLUKE Extensive Data Analysis Possibilities - 3 Ways To Analyse Measurements!

Cursors and zoom tools can be used ‘live’ while taking measurements, or ‘off line‘ on stored measurement data.  Additionally, the stored measurements can be transferred to a PC with the included software to perform custom analysis and create reports. Measurement data can also be exported to common spreadsheet programs. Store hundreds of measurement datasets and screen captures for use in reports (depending on memory capacity).
