CHE

Description

Specially designed for small-scale crosshole surveys according to ASTM 4428, this compact hammer can be used to generate both P and S waves. The hammer can be loaded down 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.
