The 640 Professional Enhanced model is a manual-focus handheld thermal imager with a 640×480 infrared detector and a Super Resolution mode that outputs 1280×960 images, for industrial and building inspection.
Thermal sensitivity is ≤35 mK and the measurement range runs -20 °C to 650 °C (-4 °F to 1202 °F) with ±1.5 °C or ±1.5% accuracy. A 24° × 19.3° field of view pairs with 0.67 mrad spatial resolution and a 30 Hz refresh rate. A manual focus ring sharpens near and distant targets, a 4.3″ capacitive touchscreen (800×480) handles menu navigation and on-screen measurement, and 1× to 6× digital zoom is available. Stills save as radiometric JPEGs and video records to MP4 and UIR with full temperature data.
It suits electrical and panel inspection, mechanical condition monitoring, and building envelope surveys.
