The PET (Pile Echo Tester) uses the Pulse-Echo method (PEM) for quick pile integrity testing (PIT) of large number of piles.
Up to 100 pile per hour can be tested with this app and the Bluetooth PET device from Piletest.
To make the pile integrity test, the pile top is tapped with a lightweight handheld hammer, The reflected wave is captured and analyzed by the PET's digital accelerometer to provide information regarding the length and shape of the pile.
The PET is fully compliant to ASTM Sonic standard D5882 and AFNOR P160-2,4 standards
