For determining the Liquid Limit of soils. This is specially useful to obtain reliable and accurate result for those soils which have low plasticity index. The percentage moisture contents determined when a cone with half angle of 15’30 minutes under a total sliding weight of 148gm penetrates 25 mm gives the Liquid Limit.
It consists of a cone fixed to a movable bearing rod. Arrangement is provided to clamps the rod at any desired position. A graduated scale is fixed to the bracket. Complete with cup 50 mm diameter and 50 mm high. Nett weight approx. 6kg.
