펠콘식 액성한계시험기 This device is used to determine a liquid limit of the soil by Fall-cone method. Let the cone with the specified tip angle and the weight fall freely into the soil surface of the sample by its own weight, and adjust the soil moisture ratio of the sample to be a desired value, and then obtain the liquid limit.
