THERMOMETER Features: Backlit display for poorly lit areas Last ten temperature readings displayed on bar graph for easy reference Enhanced optics (distance to spot ratio up to 60:1) allow measurements of smaller objects from farther away Coaxial three-dot laser sighting system highlights the true diameter of measurement spots at all distances (90% energy) Extra bright appearing 635nm laser (tested to the same safety and power standards as less bright laser sights) to clearly highlight the targeted area Close-focus option available for specialized applications MIN/MAX measurements calculations instantly computed Audible and visible HI temperature alarm for instant recognition Comfortable, overmolded pistol grip makes target sighting easy Adjustable emissivity setting (.01 increments) for more accurate measurement Durable hard plastic storage case included The Fluke 570 non-contact thermometers are ideal professional diagnostic tools for maintenance professionals requiring the most accurate temperature readings at all distances. The Fluke 570 series infrared (IR) measures surface temperatures, helping to quickly locate lubrication problems, overloads, short-circuits or misaligned and overheated equipment, reducing work and follow-up time, and improving performance. From close-up electrical connections, to distant room balancing checks, the Fluke 570 series can take IR temperature measurements with ease. Predictive maintenance professionals requiring analysis and documentation use the 574 or 576 models, with 100-point data logging and digital photographs (576-only) with the included software for graphing and analysis for follow-up reporting and documentation..
