Product FlyerImpact Echo (IE) investigations are performed to assess the condition or thickness of slabs, beams, columns, walls, pavements, runways, tunnels, and dams.
Impact Echo (IE) investigations are performed to assess the condition or thickness of slabs, beams, columns, walls, pavements, runways, tunnels, and dams.
The Impact Echo (IE) system is designed to determine the condition and thickness of concrete, wood, stone, and masonry structural members when voids, honeycomb, and/or cracks are suspected. IE investigations can also be performed to predict the strength of early age concrete if the member thickness is known. Lastly, the IE method will provide information on the depth of a flaw or defect, in addition to mapping its lateral location and extent. An advantage of the IE method over the Ultrasonic Pulse Velocity (UPV) method is that only one side of the structure needs to be accessible for testing.
Olson's IE Models are sold as add-on systems for the NDE 360 and Freedom Data PC platforms while the Concrete Thickness Gauge (CTG) is designed to be used with a Windows Device supplied by the user.

Key Features & Specifications
| Economic solution for users who already own either a Freedom Data PC or NDE 360 | Works through paint and most types of bonded tile |
| Thickness accuracy ± 2% at high resolution when calibrated on a known thickness, English or Metric units can be used | System is compact, durable, and easily transported allowing for multiple tests per day |
| Save selected test time/date and spectral thickness results for later review | Real-time waveform display while testing |
| No coupling agents required for use of test head on concrete | Software allows for more sophisticated processing |
| Easy velocity calibration at known thickness location | Works on cured, hardened concrete in air or on grade |
