434-II and 435-II Power Quality and Energy Analyzers

Key features
Analyze power quality issues, calculate the costs of wasted energy and prevent downtime with the Fluke 435-II Power Quality and Energy Analyzer.

• Advanced power quality health—At-a-glance power quality health data in real time so you can make better maintenance decisions
• Energy loss calculator—Discover the costs of energy loss specifically caused by poor power quality
• Highest safety rating in industry—CAT III 1000 V / CAT IV 600 V

The Fluke 435-II Power Quality and Energy Analyzer is designed to help you minimize downtime, quickly troubleshoot power quality issues and easily discover the costs of wasted energy. Downtime is expensive and getting the data you need to solve to critical power quality problems quickly is key. The 435-II Analyzer’s measurement process and data output has been optimized to help you access the most critical information easily.

Multiple parameters are measured simultaneously and displayed in formats that quickly describe overall power quality health. The detailed information helps you make better maintenance decisions—whether you’re trying to reduce energy waste, find the source of power quality issues or see how motor startups are affecting your electrical system. Data can be accessed as simple digital values, trend graphs (for fast insight into changes over time), waveforms, or phasor diagrams. The data can also be analyzed and organized into tabular formats. Detailed event data allows you to see the magnitude, duration and time stamping of anomalies enabling you to rapidly correlate the problems you are experiencing in your facility.

Advanced Power Quality Functions, Unprecedented Energy Analysis Capabilities
Power quality issues can affect the operation of critical loads and have a negative impact on your bottom line. Think of the Fluke 435-II Power Quality and Energy Analyzer as your insurance policy. Calculate the cost of wasted energy due to poor power quality and troubleshoot the source of power quality or motor performance issues all with a single test tool designed to give you the data you need to quickly get to the root of the problem.
