Status: 1742 / 1746 / 1748 Current Production — 1740 / 1743 / 1744 / 1745 Discontinued
Overview
The Fluke 1740 Series Power Quality Loggers provide IEC 61000-4-30 Class A compliant power quality logging for utility-grade studies and regulatory compliance verification. These instruments capture all standard PQ parameters including voltage, current, power, energy, harmonics, flicker, dips, swells, and transients over extended deployment periods. The current models (1742, 1746, 1748) feature enhanced memory, faster data transfer, and compatibility with Fluke Energy Analyze Plus software. Legacy models (1740, 1743, 1744, 1745) remain in active service at utilities and industrial facilities worldwide.
