Compact, rugged and reliable, the Fluke
1740 Series three-phase power quality
loggers are everyday instruments for
technicians who troubleshoot and
analyze power distribution systems.
Capable of simultaneously logging up
to 500 parameters for up to 85 days and
capturing events, the Fluke 1740 Series
helps uncover intermittent and hard-to-
nd power quality issues. There are three
models to choose from to meet your
basic or advanced power logging needs.
Fluke 1743: IP65 waterproof monitor
for logging the most common power
parameters including V, A, W, VA, VAR, PF,
energy, icker, voltage events and THD.
Fluke 1744: Includes the same features
as the Fluke 1743. In addition to common
power parameters, the Fluke 1744 also
measures voltage and current harmonics,
interharmonics, mains signaling,
unbalance, and frequency.
Fluke 1745: Advanced IP50 power quality
logger with the same measurement
capability as the 1744, plus real-time LCD,
ve hour UPS.
