The Extech IRT500 IR Thermal Scanner is designed with a dual laser, audible/visual alarm feature, 5 preset threshold settings, and 3 color LED indicators to make it easy to locate hot and cold spots quickly by scanning the area being tested. Just point at your target and scan. The three-color LED indicates High (red), normal (green), or low (blue) when scanning for temperature irregularities. The audible alarm increases as temperature increases or decreases. A dual laser system indicates ideal measuring distance by converging at 20 inches (50.8cm) to conform to a 1 inch (2.5cm) target spot.
