Concrete strength and uniformity evaluation using optical rebound hammer technology


Accurately test the widest range of concrete strength classes.

Work with the built-in standardscompliant conversions or your own custom material conversions.


A mobile app that lets you annotate measurements with voice, photos, and comments.

Generate reports and share them instantly. Access your data from anywhere, anytime.


Fully assess an entire test region of concrete in less than 10 minutes—saving you days of laborious effort compared with exclusively using coring.
