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.
The VAKKA sensors are fully embedded, durable, and waterproof wireless monitoring devices used to measure the internal temperature and relative humidity of newly cast concrete up to a depth of 3 meters.
The RapidAir is an image analysis system for automatic and quick determination of the air void structure parameters in hardened concrete according to the linear traverse method (procedure A) or the point count method (procedure B) as per ASTM C457.
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.
Merlin is used to measure the bulk electrical resistivity, or its inverse, the bulk electrical conductivity, of saturated specimens or cores according to ASTM C1876 “Standard Test Method for Bulk Electrical Resistivity or Bulk Conductivity of Concrete”.
The RAT (Rapid Alkali Test) is a portable kit that measures the amounts of sodium and potassium ions that contribute to deleterious alkali-silica reaction (ASR) if reactive aggregates are present in concrete.
4-probe monitoring system for early warning of the onset reinforcement corrosion.
The ERE-Probe is a half-cell reference electrode to be embedded in concrete for monitoring of corrosion activity of the steel reinforcement.
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.
