BOREHOLE SEISMIC ENERGIZER MODEL “CHE”CrossHole Energizer www.pasigeophysics.com “CHE” BOREHOLE SEISMIC ENERGIZER Specially designed for small-scale cross-hole surveys, this compact hammer can be used to generate both P and S waves.The hammer can be downloaded using the steel cable and clamped to the requested depth by a pneumatic clamping system manually controlled by a lever from the surface; simply pushing up the steel cable to execute the first shot, the trigger installed on the energizer will start the acquisition for the “P/S”. After that you will have to drop the mass to make the acquisition with inverse polarity. TECHNICAL FEATURES SYSTEM COMPATIBLY: Borehole Geophones and the borehole energizer “CHE”, model “DHTG” and “GFA ” are compatible with all PASI’s seismic data acquisition systems.
