The PIT performs wave equation-based non-destructive foundation investigations known as Low Strain Impact Integrity Tests or Low Strain Dynamic Tests. This test may be performed by the Pulse (or Sonic) Echo or Transient Response Methods. With the PIT, any form of the test is performed fast, potentially making it possible to test every pile on a job site.
The PIT test consists of attaching one or two accelerometers to the foundation and using a hand-held hammer to impact it. The PIT collects the acceleration data and displays curves that reveal any significant changes in cross section that may exist along the shaft. The PIT-W software post-processes the data and generates reports, while the PIT-S software simulates a PIT test and performs simplified signal matching to assess the shape of the foundation.
The Pile Integrity Tester is available in several configurations to match the needs of each user. Find out which model is right for you here.
PIT-QV and PIT-QFV have a large screen and read data from traditional (cabled) accelerometers and/or instrumented hammers.
All models of the Pile Integrity Tester are battery powered, operated through a high visibility touch screen, and include a Fast Fourier Transform (FFT) feature and a license of PIT-W Standard Software. All comply with ASTM D5882 (Low Strain), ASTM D8381 (Parallel Seismic), and many other codes and specifications.

PIT-W Standard
PIT-W Standard version is a universal license with no restrictions
The PIT-S software lock license is not a shared license and only good for one user and on one computer at a time. How you activate the license is by a USERNAME and LICENSE NUMBER.
The PIT-W Professional software lock license is not a shared license and only good for one user and on one computer at a time. How you activate the license is by emailing in your site code and we will reply with a site key.
We offer free license transfers for all single‑user software locks, as long as the original installation is properly deactivated. A valid deactivation code must be provided when moving the license to a new computer.
If a deactivation code cannot be generated due to computer failure, reformatting, or system malfunction, a reactivation fee will be required to issue a new activation.
This policy ensures the protection and proper management of all licensed software.
