Digital Liquid Limit Device with Casagrande Cup Counter

Motor-driven Casagrande liquid limit machine with electronic blow counter for consistent Atterberg limit testing of fine-grained soils. Used in highway material labs and soil classification work.

Specification

The device raises and drops a brass cup 10 mm at two drops per second, and an electronic counter registers each blow, removing operator counting errors. Soil plasticity data obtained helps classify soils for road subgrades and earthen structures. The ebonite base meets standard hardness requirements.

Features

• Motorised cam drive at 2 blows per second
• Digital preset counter with auto stop
• Hardened brass cup with adjustable height gauge
• Hard rubber base of 80-90 Shore A hardness
• Grooving tools for casagrande and ASTM types included
