E-Saximeter (E-SAX)

E-Saximeter (E-SAX) Handheld instrument registering relevant pile driving parameters, calculating stroke for open end diesel hammer or hammer blows per minute (BPM), for an accurate pile driving log. Counts hammer blows, and equivalent blows per minute for all hammer types; calculates stroke height for diesel hammers Provides a drive log of blow count as a function of depth Results are downloaded from the E-SAX to your computer Optional accessories allow for impact velocity measurements to compute kinetic energy and depth measurements
