OVERVIEW & SPECIFICATION
Fluke 435 II Power Quality and Energy Analyzer as your insurance policy. No matter what goes wrong in your facility, with the 435 II you will always be prepared. Equipped with advanced power quality functions and energy monetization capabilities, there is no electrical issue this model can’t handle.
Applications
- PowerWave data capture – capture fast RMS values to see every waveform so you can determine how the voltage, current and frequency values are interacting
- Power inverter efficiency – Power inverter efficiency
- Energy monetization – calculate the fiscal cost of energy waste due to poor power quality
- Energy assessment – quantify the before and after installation improvements in energy consumption to justify energy saving devices
- Frontline troubleshooting – quickly diagnose problems on-screen to get your operation back online
- Predictive maintenance – detect and prevent power quality issues before they cause downtime
- Long-term analysis – uncover hard-to-find or intermittent issues
- Load studies – verify electrical system capacity before adding loads
