Fluke 68 Thermometer User Manual


 
More demanding applications require more precise
measurement and specialized features. That’s when
predictive maintenance professionals reach for the
Fluke 570 series. An even wider temperature range,
more powerful optics, a more precise sighting system,
faster response time and adjustable emissivity make
the 570 series the most accurate IR thermometer on
the market.
Advanced sighting
An extra bright coaxial three-dot laser sighting
highlights the center and diameter of the
measurement spot. The laser sighting appears twice
as bright to the human eye as a standard laser
sighting (while maintaining the same safety rating as
less bright lasers), making accurate sighting easier in
a variety of lighting conditions and distances.
Fluke 572 and 574
Additional features of the 574
For maintenance professionals who need to monitor,
capture, analyze and report temperatures and
temperature trends, the 574 comes with 100-point
onboard data logging capabilities, customizable log
location names, programmable emissivity settings
and PC software for condition monitoring and process
control.
