Clayish soil changes from plastic state to liquid state depending on its water content.

In order to determine the passage from the first to the second state, standards recommend that a test with the cone penetrometer be carried out. Allow to drop and from a fixed height within a definite time on the soil sample. The water content percentage which gives a 20mm penetration is assumed to be the “Liquid Limit”

The digital electronic release model has a 0.1mm graduation and automatic zeroing. The base has leveling screws and provision is made for adjusting cone height in relation to the sample.
