  • FLUKE 1734-INTL 3Phase Electrical Energy Logger / Wireless

    # 1734-INTL

    • Trace the energy utilization profile at your facility
    • Help identify energy-saving opportunities
    • Get the data you need to act accordingly.
    • 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
    • Optimized user interface: Capture the right data every time with quick, guided, graphical setup and reduce uncertainty about your connections with the intelligent verification function
    • Complete “in-the-field” setup through the front panel or Fluke Connect: No need to return to the workshop for download and setup or to take a computer to the electrical panel
    • Energy Analyze Plus application software: Download and analyze every detail of energy consumption with our automated reporting
