More than just an IR Thermometer, this IR Thermal Scanner is designed with a dual laser, an audible/visual alarm feature, 5 preset threshold settings (1°, 5°, 10°, set Min, set Max), and 3-color LED indicators to make it easy to locate hot and cold spots quickly by scanning the area being tested. Users simply point at targets and scan. The 3-color LED indicates High (red), Normal (green), or Low (blue) when scanning for temperature irregularities. Audible alarm increases as temperature increases or decreases. Fast 150 millisecond instantaneous response for capturing spikes in temperature. Dual laser indicates ideal measuring distance (approximately 20 in.) where the 2 lasers converge to a 1 in. target spot. Tilt adjustable LCD display with bright white backlight and dual barographs. Trigger lock function provides continuous use for scanning large areas. Comes with 9-Volt battery, carrying case, and user manual.
