Fluke 1730 Three-Phase Electrical Energy Logger measures voltage, current, power, power factor and associated values. This energy logger will help discover energy waste through profiling energy usage across a facility and help identify opportunities to save energy. With the new Energy Analyze software package it will allow you to compare multiple data points over time and build a complete picture of energy usage. The 1730 has a LCD touch panel screen, and a higher pixel resolutuion than that of the older 1735 version. This unit is smaller in design to allow it to test in tighter spaces and weighs a pound less. This unit also comes with 2 USB ports, one for PC connection and one for USB thumb drive.
