The Hand-Operated Liquid Limit Device is designed to determine the liquid limit of soils. The hard rubber base is formed in a mould to maintain the uniformity of hardness, size and density of all devices. Precision moulded cam control parts and nylon bearings provide accurate cup drop and smooth operation.
The Plastic Grooving Tool is used to control the width of the soil groove in the liquid limit cup. With traditional metal grooving tools, the cups get scratched; the costly metal tools get worn, giving inaccurate test results.
