Casagrande Method Disc Type Liquid Limit Apparatus is used to determine the moisture content of soil transitions from plastic state to liquid state under standardized conditions. The apparatus consists of a brass cup, a mechanism for controlling the rate of rotation, a counter, and a grooving tool. During the test, the soil sample is mixed with water to form a paste, and the paste is then placed in the cup. The cup is rotated on a carriage at a standardized rate, and a grooving tool is used to create a groove in the soil paste. The number of blows required for the groove to close over a certain distance determines the liquid limit of the soil.
Available in 3 models:
1.Hand operated through the crank.
2.Electrically operated at 120 blows per minute based on standard.
3.Fully automatic operation with LCD touch screen.
