Casagrande Liquid Limit Device for Atterberg Limits Testing
The Casagrande Liquid Limit Device is designed to determine the liquid limit of fine-grained soils by establishing the relationship between moisture content and the number of blows required to close a standard groove. This test identifies the moisture content at which soil changes from the plastic state to the liquid state, providing essential data for soil classification and geotechnical engineering.
The BESMAK Casagrande Liquid Limit Device is available in both manual and motorized versions to meet the requirements of quality control laboratories, research facilities, and geotechnical engineering applications.

Manual and Motorized Operation
The manual model features a precision crank mechanism with a mechanical revolution counter for accurately recording the number of blows during testing.
The motorized model provides fully automatic operation at a constant testing speed, minimizing operator influence while improving repeatability and efficiency for high-volume laboratory testing.
Liquid Limit Test Method
The Casagrande Liquid Limit Device determines the moisture content at which a soil sample flows under standardized impact conditions. During the test, a standard groove is formed in the prepared soil specimen using the appropriate grooving tool. The brass cup is repeatedly dropped until the groove closes over the specified distance.
The relationship between the number of blows and the measured moisture content is then used to determine the liquid limit, which is an essential parameter for soil classification and geotechnical analysis.
