The Fluke 1775 3-Phase Power Quality Analyser is a rugged, portable device for troubleshooting power quality. The compact size and power supply from the measurement line makes it a versatile tool for live measurements and long-term logging.

Fluke 1770 Series Three-Phase Power Quality Analysers eliminate the complexities of power quality logging, troubleshooting, and analysis. Engineered to be the faster, easier way to perform power quality studies, the 1770 Series offers automatic measurements, a straightforward user interface and setup, best-in-class specifications, and a simplified reporting platform. The instrument can also be powered directly from the measurement circuit, eliminating the need to find a power outlet or use a lengthy extension cord.

The Fluke 1770 Series are 2-in-1 devices that combine the trouble-shooting functionality of a power quality meter with the robust analysis and logging capabilities of a standalone power quality analyser - in a single, easy-to-use, handheld device.
