Introducing powerful NEW enhancements to our "Concrete Thickness and Flaw Gauges" — the CTG 1T-SW and the CTG1TF-SW for testing concrete thickness, integrity and quality.

The two models listed above incorporate the capabilities of our existing CTG, but adds a 20cm long arm to the front of the test head with a second displacement transducer to also allow for Spectral Analysis of Surface Wave testing. The main advantage of the CTG-1T-SW Model is that it can be used to calibrate the concrete velocity for thickness tests using the CTG without requiring a corehole. This unit can also be used to collect simple SASW data to allow subsequent office analysis of the data (using included WINTFS software) to estimate surface-opening crack depth and concrete quality versus depth. It will display a plot of velocity vs. wavelength on its screen (dispersion curve) with a quality factor for the uniformity of the velocity result for the concrete depth range of interest. It can also be used for correlating strength vs. velocity in the field to laboratory tests of concrete specimens (cubes, beams or cylinders) with Impact Echo (IE) or Ultrasonic Pulse Velocity (UPV) measurements.

The CTG-1TF-SW Model combines Impact Echo (IE) thickness/flaw detection with SASW velocity measurement for the most powerful concrete thickness, concrete integrity and concrete quality testing, hands down.
