ASTM Liquid Limit Machine (Hand-operated + Automatic Counter)
Supports the following standards: ASTM D4318
Atterberg Limits testing is widely used in the design stage of construction to ensure that the soils being used exhibit the proper consistency to support structures even as their moisture levels change. Soils for engineering use are often classified based on properties relative to foundation support or how they might perform under pavements and in earthworks.
Humboldt manufactures a series of machines to perform the required testing.
The hand-operated liquid limit machine (model H-4228) features a mechanical revolution counter attached to the shaft to register the number of drops in the liquid limit cup.
