    • 434 Series II Power Quality Analyzer

      Calculate energy loss in dollars
      The new 434 Series II Three-Phase Power Quality Analyzer offers the best in power quality analysis and introduces, for the first time ever, the ability to monetarily quantify energy losses. The Fluke 434 II is the ideal tool for energy logging. Utilizing the new Energy Loss Calculator function, the 434 II measures the fiscal cost of energy wasted due to poor power quality. This energy monetization capability allows you to identify the most energy-wasteful areas of your facility so you can determine potential energy saving solutions. Add basic power quality measurements to the package and you're got yourself one powerful troubleshooting tool.

      AutoTrend - Quickly see the trend
      Unique AutoTrend gives you fast insight into changes over time. Every displayed reading is automatically and continuously recorded without having to set up threshold levels or interval times, or having to manually start the process. You can quickly view trends in voltage, current, frequency, power, harmonics or flicker on all three phases plus neutral. And you can analyze the trends using the cursors and zoom function mdash; even while background recording continues.

      SystemMonitor - Check performance against EN50160 with ease
      With a single push of a button, the unique System-Monitor gives you an overview of power system performance, and checks the compliance of incoming power to EN50160 limits or to your own custom specifications. The overview is shown on a single screen, with color-coded bars clearly indicating which parameters fall outside the limits.
