Thermal imaging cameras provide a non-destructive method of quickly identifying subsurface defects and areas of deterioration on a wide range of materials. The infrared cameras detect temperature and thermal gradients, allowing defects such as voids, cracks, and delaminations to be found for maintenance and repair assessment. Thermal cameras are particularly useful during asphalt placement by identifying the temperature gradients that help determine rolling patterns. Models are available in varying temperature ranges and resolution to address specific material evaluation requirements.
Thermal image enhancement on FLIR® models adds key details from the visible spectrum camera to the infrared image on the display. The basic model displays live minimum/maximum temperatures.
