Working Principle
The geotextile specimen is horizontally clamped in the clamping ring. A steel cone of specified mass is dropped from a height of 500 mm onto the specimen, creating a hole. A small, graduated measuring cone is then inserted into the hole to measure the degree of penetration (hole size).
