A world first – Heavy penetrometer automatically adapts its impact energy to the soil hardness

The Variable Energy option converts the GRIZZLY® from a constant dynamic energy penetrometer (DPSH) into a Variable Energy version, providing high resolution, reliability and accurate measurements in soft or very soft soils whilst automatically adapting to the resistance of the soils encountered during the test. Hence with the Variable Energy option, the GRIZZLY® DPSH is very good at measuring the interface between hard and soft zones which are of great interest to geotechnical engineers.
