The Fluke 66 and 68
Infrared Thermometers
Non-contact temperature measurement
Technical Data
The professional’s diagnostic tool
The Fluke 66 and Fluke 68 non-contact thermometers
are the ideal professional diagnostic tools for HVAC
technicians performing room balance checks, electricians
evaluating electrical connections and auto mechanics
diagnosing catalytic converters. This handheld portable
tool enables professionals to research heating and venti-
lation problems, monitor the status of electrical motors
and electrical panels and diagnose car malfunctions with
ease. They measure surface temperatures, helping to
quickly locate potential blockages or malfunctioning
systems reducing work time and improving performance.
The 60 series thermometers feature:
•
Laser guided sighting system for easy targeting with
1 % accuracy.
•
12-point data logging.
•
Advanced optics to measure smaller targets at greater
distances.
•
Adjustable emissivity for more accurate temperature
measurements.
•
Selectable MAX, MIN, DIF and AVG functions that
display values instantly with Hi/Lo Alarm.
•
Temperatures up to 760 ºC (1400 ºF) (68).
Use the Fluke 66 within 5 m (15 ft.) of the intended target.
