FLUKE 1736／1738 Three-Phase Power Loggers | Over 500 power quality parameters, harmonics to 50th, IEC 61000-4-30 Class S, CAT IV 600 V

FLUKE 1736／1738 Three-Phase Power Loggers: Long-Term Logging of Over 500 Parameters

Overview

The 1736 and 1738 automatically capture and log over 500 power quality parameters and digitally verify and correct common wiring errors. The 1738 is the advanced version with waveform capture, PQ Health (EN50160) and Fluke Connect measurement module support as standard; the 1736 requires a purchased upgrade license for these functions.
