574-NI Nonincendive
Model
When safety is a concern and
data logging and downloading
are required, the Fluke 574
Nonincendive (NI) model
thermometer is the product to
choose. It has the same great
features as the standard 574
model thermometers with the
extra confidence of a Factory
Mutual approval for use in
hazardous environments*.
The Fluke 574-NI thermometer,
does not to release enough electrical or thermal energy to
ignite flammable gases or vapors under normal operational and
environmental conditions.
*See specification table for details.
Advanced Sighting
Accurate measurements depend in part on
accurately sighting a target. Fluke 570 series
thermometers are the only thermometers with
a sighting system designed to precisely track
the infrared path as seen by the sensors. This
enables the advanced coaxial three-dot laser
sighting to accurately show both the center
and the edges of the spot being measured,
regardless of the thermometer’s distance from
the target.
This laser sighting also appears twice as
bright to the human eye as normal lasers
(while maintaining the same safety rating as
less bright lasers), making precise sighting
easier in a variety of lighting conditions and
distances.
Close Focus Option
The Close Focus (CF) option lets you accurately measure very
small areas at the focus point – where the IR beam narrows.
Paired with the advanced coaxial laser sighting system,
extremely small objects 6 mm (0.24 in) at 300 mm (11.4 in)
can be easily measured. Ideal for electrical maintenance and
refrigeration troubleshooting.
Visualize, systematically maintain and analyze temperature data using Windows®
compatible software and a Fluke 574 or 574-NI IR thermometer.
Software for Condition Monitoring and
Process Control

Maintenance, Repair and
Operations (MRO) systems
and other database programs
Easily see
temperature trends
and potential
equipment problems
by graphing data
accumulated with
the unit’s data
logging feature.
The software
makes it easy
to error-proof
inspection routes
by giving names,
alarm points and
emissivities to
locations.
The 574 can be used
to monitor, graph,
and record real-time
temperature changes
with the software.
The software
provides a
convenient way to
export temperature
data files in a format
that can be used by
programs such as
Access®, Excel®, and
condition monitoring
programs.
