The FLUKE-566 is a non-contact infrared thermometer designed for professional diagnostic applications in HVAC, electrical, and automotive fields. It features a laser-guided sighting system with 1% accuracy, advanced optics for measuring smaller targets at greater distances, and digitally adjustable emissivity (0.1 to 1.0) for precise temperature measurements. The device offers a temperature range of -32 to 600°C (-25 to 1100°F), a response time of =0.5 seconds, and 12-point data logging capability with MIN, MAX, AVG, and DIF functions. With a 30:1 distance-to-spot ratio at the focal point and typical targeting distance of 5 m (15 ft.), the FLUKE-566 enables technicians to quickly locate blockages, monitor electrical systems, and diagnose equipment malfunctions while reducing diagnostic time and improving overall performance.
