We utiize NO-DIG technology, which was developed based on NTT's R & D results, to continue to take part in improving social infrastructure efficiency, as well as to contributing to global environmental protection.
In order to use the concrete structures safely and for long time, it is very important to understand its state (thickness, cracks, exfoliation, etc). This device, with functions that have not been available before, is ultrasound inspection equipment that can measure accurately the concrete internal features.
■Can measure up to 2m depth by noise reduction function
■Can measure concrete thickness and crack's depth
■Can easily analyze the measured wave with automatic recognition function
■The influence of steel reinforcements or aggregates is minimized by high speed average process
■Core sampling is not required therefore the degradation progress can monitored
