The concrete thickness tester is a handheld, battery powered non-destructive testing system. Can be used for testing the thickness of concrete slabs, pavements, tunnel linings, walls, and other surface structures. The testing principle is the same as that of IE impact echo testing. This instrument has an easy-to-use menu. It is based on the principle of impact echo to measure the thickness of concrete. During actual measurement, the default concrete parameters built into the instrument can be directly used. CTG can be calibrated on a concrete slab with a known thickness (by drilling or coring) to obtain the wave velocity of the concrete to be tested, and then testing can begin. More than 60 CTG tests can be conducted per hour without drilling or excavating. Using Olson's concrete thickness defect tester can save time and costs.

characteristic

● Integrated testing probe, built-in displacement sensor and solenoid impactor

No coupling agent is required during testing

It can be tested on hardened concrete in the air and can also be used for concrete on the ground

It is also possible to test ceramic tile structures with paint or good bonding on the surface (or check if the ceramic tile bonding is good)

● Semi transparent LCD display screen for easy reading outdoors, with convertible backlight for indoor use

● British or metric thickness display

At known thicknesses, the wave velocity is easy to calibrate or use Olson's default parameter settings

● The testing time, date, and thickness structure can be downloaded to a PC

Thickness data can be entered into popular spreadsheet software

The CTG-1TF model outputs a thickness summary table and the data obtained through post-processing using WINTFS-I or WINTFS-SASW software on a Windows 2000 or updated PC computer
