The portable Light Weight Deflectometer TERRATEST 9000 LWD meets the specifications of ASTM E2583 and will improve your quality control process. The device is designed to check the stiffness and compaction quality of unbound layers and partially bound material of soil. The test may be conducted by a single person in less than one minute without using a truck. The results may be provided immediately at the construction site.
TERRATEST 9000 LWD provides a wide range of possibilities by utilizing a high-precision center geophone, two additional satellite geophones, various load plate diameters, additional falling weights, and a variable falling height supported by a high-precision load cell.
The test procedure is operated via an iOS/Android APP included in the package. No extra electronic device is necessary, and all the test data will be stored on your smartphone or tablet.
