Foundation Test Gauge (FTG)
Measure foundation depth and integrity: coring, drilling, or excavating is not required.
The Foundation Test Gauge (FTG) is a small laptop or tablet powered, nondestructive system for measuring the depth and integrity of drilled shafts, driven piles, concrete mats, and timber foundations using the SONIC ECHO principle (also called Pile Integrity Testing or PIT, Low Strain Integrity, and other names).
Requires only minimal training for use — connect the Foundation Test Gauge to your laptop or tablet and start testing with Olson's FTG software. The system includes everything you need for testing except for a user-provided Windows 7 - 10 laptop or tablet - including an accelerometer receiver and a non-instrumented hammer.
NOTE: Sonic Echo testing is available as an add-on for the Freedom Data PC and the NDE 360 platforms.
