Product overview: Fluke 1732 and 1734 Three-Phase Electrical Energy Loggers
 

Three phase power measurements made easy

The Fluke 1732 (without wifi) and 1734 (with wifi) Three Phase Electrical Energy Loggers deliver easy to use three phase power measurement data for discovering sources of electrical energy waste, overloaded circuits and help you perform routine load studies. Discover when and where energy in your facility is being consumed - from the service entrance to individual circuits. Access and share three phase power data remotely with your team via the Fluke Connect® app so you can maintain safer working distances and make critical decisions in real-time, reducing the need for protective equipment, site visits and check-ins.

Profiling energy usage across your facility helps you identify opportunities for energy savings, and provides you with the data you need to act on them. The new Energy Analyze software package allows you to compare multiple data points over time to build a complete picture of energy usage, which is the first step to reduce the cost of your energy bill.

• Key measurements: Automatically capture and log voltage, current, power, power factor, energy and associated values
• Fluke Connect® compatible: View data locally on the instrument, via Fluke Connect mobile app and desktop software or through your facilities’ WiFi infrastructure
• Convenient instrument powering: Power instrument directly from the measured circuit
• Highest safety rating in the industry: 600 V CAT IV/1000 V CAT III rated for use at the service entrance and downstream
• Measure all three phases: With included 3 flexible current probes
• Comprehensive logging: More than 20 separate logging sessions can be stored on the instruments. In fact, all measured values are automatically logged so you never loose measurement trends. They can even be reviewed during logging sessions and before downloading for real-time analysis
• Optimized user interface: Quick, guided, graphical setup ensures you’re capturing the right data every time, and the intelligent verification function indicates correct connections have been made, reducing user uncertainty
• Bright, color touch screen: Perform convenient in-the-field analysis and data checks with full graphical display
• Complete “in-the-field" setup through the front panel: No need to return to the workshop for download and setup or to take a computer to the electrical panel
• Fully integrated logging: Connect other Fluke Connect devices to the Fluke 1734 to simultaneously log up to two other measurement parameters, virtually any parameter available on a Fluke Connect wireless digital multimeter or module*
• Energy Analyze Plus application software: Download and analyze every detail of energy consumption with our automated reporting
