The Fluke 1736 and 1738 Three-phase Power Quality Loggers are versatile, three-phase Fluke Connect-compatible power loggers for conducting energy, load and power quality studies.
  • Key measurements: Automatically capture and log voltage, current, power, harmonics and associated power quality values, and capture dips, swells, and inrush currents with event waveform snapshots and high-resolution RMS profiles
  • Convenient instrument powering: Power instrument directly from the measured circuit
  • Energy Analyze Plus application software: Download and analyze every detail of energy consumption and power quality state of health with our automated reporting and use the integrated power quality health summary to get an at-a-glance understanding of system health


  • Provides the baseline multimeter features you need for troubleshooting and repairing electrical and electronic systems
  • Delivers accurate true-RMS AC current and voltage plus frequency, capacitance, resistance, continuity and diode measurements
  • Increases productivity with manual and automatic ranging, Display Hold, Auto Hold, and Min/Max-average recording


  • Intrinsically safe infrared and contact thermometer
  • Meets intrinsically safe certifications in Class I Div. 1 and Div. 2 or Zone 1 and 2 hazardous environments
  • Measures temperatures from -40°C to 800°C (-40°F to 1472°F)
  • Comes with a conductive case to safely carry the IR thermometer into hazardous areas
  • Offers a distance-to-spot ratio of 50:1


Solve power problems you meet in your daily work, now that electrical loads in industrial and commercial buildings are often too complex to be calculated by the classical model of power.
Understand the major elements that affect power quality with our online webcast and supporting guidebook:
  • particularly inductive loads
  • harmonic distortion
  • three-phase power unbalance


  • Identify complex signal problems fast
  • Supports accurate measurements on VFDs using a low-pass filter
  • Captures intermittents as fast as 250 µS with Peak Capture
