The SPT Analyzer measures the energy transferred into an instrumented SPT rod during a Standard Penetration Test (SPT). This permits the adjustment of the measured N-value to the normalized N60 for standard 60% energy transfer into the rods in accordance with ASTM D4633. Compensating for widely variable efficiencies from different SPT rigs and hammer types improves the reliability of soil strength estimates used in geotechnical designs.
