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.
An integrated shipboard power measurement system analyzes according to MIL-STD 1399 to automatically give a full evaluation of voltage, current and power according to the standard. Multiple parameters are measured simultaneously and are displayed in formats that quickly describe overall power quality health. Data can be quickly accessed as simple digital values, viewed as trend graphs that give fast insight into changes over time, or viewed as waveforms and phasor diagrams or analyzed. Data can also be organized into tabular format for viewing events where the magnitude, duration and time stamp enable rapid correlation to the problems being experienced.
