Fluke 574 Fluke 572, 574, and 574-NI Infrared Thermometer Datasheet - Page 2

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 Display • 100-point onboard temperature data logging capability • 30 preset common material emissivity values • Adjustable emissivity values (0.01 increments) • Customizable log names, alarms, and emissivity 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.
