The Fluke 66 and 68 Infrared Thermometers Non-contact temperature measurement Technical Data The professionals 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 C (1400 F) (68, 68IS). * Intrinsically Safe model available (68IS). Optical resolution The laser sighting system guides measurements to the right target and indicates the approximate center of the measurement area. (D:S = distance to spot using 90 % encircled energy at focal point). * The 68IS model is available for the noncontact temperature monitoring needs of potentially explosive or flammable environments. *Approved by Factory Mutual Research, a USA organization, for use in hazardous locations. The 68IS approval does not apply to atmosphere containing coal dust, grain dust, metal dust or fibers. Check your national and company regulations to determine if this approval is appropriate for your situation.
