Fluke 434 Three-Phase Power Quality Analyzers - Pinpoint power quality problems faster, safer and in greater detail.
These three-phase power quality meters help you locate, predict, prevent and troubleshoot problems in power distribution systems. These easy-to-use power quality tools are a “must have” for any person who maintains or troubleshoots three phase power. The new IEC Class A standards for flicker and power quality are built right in to take the guess work out of power monitoring.

Applications
* 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
* Quality of service compliance – validate incoming power quality at the service entrance
* Long-term analysis – uncover hard-to-find or intermittent issues
* Load studies – verify electrical system capacity before adding loads
* Energy assessments – quantify energy consumption before and after improvements to justify energy saving devices
