Soil liquid plastic limit joint measuring instrument

The soil liquid plastic limit joint measuring instrument is used to determine the liquid limit, plastic limit, plasticity index, natural consistency and other indicators of soil. The above soil indicators are obtained by measuring the depth at which a standard cone with a certain weight is vertically inserted into the sample within a specified time. Solved the problem of manually determining whether the standard cone contacts the soil sample during experiments for many years, and achieved automation and digitization of the experimental process. A modern soil testing instrument with high precision, stability, and reliability has been provided for the fields of highways, municipal engineering, construction, and water conservancy in China.
