Intelligent Crack Width Gauge/Intelligent Crack Monitoring Instrument/Crack Width Gauge Model: HFTLF-2

The HFTLF-2 (intelligent) crack width gauge can be widely used for quantitative detection of crack width in bridges, tunnels, buildings, concrete pavements, metal surfaces, and other areas. The device mainly consists of a handheld color LCD screen host and a color microscope magnifying probe (with a 1.5-meter connecting cable). During measurement, the program automatically scans and captures cracks, and displays the width value of the cracks in real time on the display screen. It can also take photos of the cracks needed (crack images, width data, scale, magnification, crack number and other image information are saved in the crack photos). The crack photos are in standard BMP format and are directly stored in any USB drive, making it convenient for users to further analyze images or print archives.
