The impact-echo method is based on monitoring the periodic arrival of reflected stress waves generated by a small mechanical impact. Unlike traditional ultrasonic pulse velocity testers that require access to both faces of a member and it is not possible to determine the depth to anomalies, DOCter requires access to only one face and is able to obtain information on the depth of internal flaws or the thickness of a solid member.

Echolyst is an advanced data acquisition and data analysis software for the impact-echo method. It is used along with the Mirador system or other commercially available hardware for Impact-Echo.

Compact, hand-held, light weight, coupling-free instrument for measuring the of ultrasonic pulse velocity (UPV) of longitudinal stress waves propagating within concrete.

A compact, hand-held, light weight instrument for measuring the ultrasonic pulse velocity (UPV) on the concrete surface.

The MIRA 3D is the advanced version of the well-known, state-of-the-art, MIRA Ultrasound Tomographer for depth measurements and flaws detection in elements of concrete structures. It incorporates the Full-Matrix-Capture (FMC) data collection technique and Total Focusing Method (TFM) processing algorithm to compute the data acquired and directly reconstruct 3D images of the reflecting interfaces within the volume of the object below the antenna at each test position.
