Concrete Thickness Gauge 2

It is now easier than ever to verify the thickness and integrity of concrete flatwork. Drilling, coring and excavations are now obsolete. Save buckets of time, effort and money by simply using the CTG-2 instead.

No specialized knowledge or training is required. The CTG-2 comes ready to use straight out of the case, with inbuilt default parameters. Great accuracy is achieved through calibrating against your specific concrete type.

Use your own Windows 7, 8  or 10 Laptop/Tablet* and simply connect the CTG-2 to directly view live measurement recordings, via the WinCTG-2 Software. Thickness and flaw information can also easily be transferred to spreadsheets or to your reports.

*Please note Tablet is not included

Applications

Impact Echo testing can be used for:

• Depth, lateral location and extent of internal flaws
• Verification of Concrete Slab Thickness
• Usable on non-concrete materials depending on the material’s internal structure
• Quality Assurance checks
• Can be used to predict early age strength

Features

• Non-destructive and non-invasive
• Designed for Site, Rugged and Lightweight
• No coupling agents required
• Intuitive tablet interface for settings/results
• Calibration takes seconds for high accuracy
• View live Thickness Data and Sound Waveforms
• Customise your Grid Test Area
• WinCTG-2 software conversion to spreadsheet
• Frequency Spectra reveals presence of flaws with depth and lateral location.
• Penetrates cured paint and bonded tile

Operation

Concrete Thickness
Impact Echo relies on an estimation of p-wave velocity through concrete to determine thickness. Thickness measurements are obtained when the test head is applied to the concrete surface and triggered.

Calibration Process
Default settings are customised to standard concrete and generally produce results within ±10% accuracy. Accuracy of ±2% is achieved when the p-wave velocity is calibrated on-site against a slab with known thickness.

Data Transfer
WinCTG-2 software works alongside Windows 7 or 8, converting frequency and thickness data into most spreadsheet formats for further analysis and reporting.

WinCTG-2 Analysis Software
The Windows based WinCTG-2 allows data and measurement setting review. Customised test grids can be set up using X and Y coordinates from your point of reference. Live field data can be viewed while testing.
