Atterberg Limits testing is widely used in the design stage of construction to ensure that the soils 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.
This model, the H-4226.5F (Motorized Liquid Limit Machine) gives uniform testing with greater accuracy.
Features:
