SIR-1 Model [Base Model]
Description: Test For: Applicable On:

Complete system for testing slabs-on-grade, and then create 2-D contour maps by importing the results table into popular spreadsheet programs. These renderings are often a valuable resource for isolating and repairing voids below slabs-on-ground.

This model includes a vertical geophone transducer for flat slabs, and instrumented hammer, cables, and the acquisition/processing software.
