Motorized Liquid Limit Machine with Counter

Motorized Liquid Limit Machine with Counter

Achieve Consistent and Repeatable Liquid Limit Test Results

The Motorized Liquid Limit Machine with Counter provides unparalleled accuracy and consistency for determining the liquid limit of soils. Its specialized geared motor ensures a constant operating speed of 1.9-2.1 drops per second, eliminating the variability associated with manual operation and adhering strictly to testing standards. An integrated, easy-to-read counter automatically tracks the number of drops, allowing the operator to focus on the sample's response without manual counting.

What is the Liquid Limit?

The Liquid Limit is a fundamental measure of soil consistency. It represents the specific water content at which a soil transitions from a liquid to a plastic state. This value is determined by jarring a soil sample in a standardized brass cup until a groove cut into the sample closes over a specific distance.

Superior Design and Operation

This machine is built for precision and durability. It features a solid brass cup suspended from a carriage, meticulously designed to control its fall to exactly 1cm onto a hard rubber base.

Key features include:

• Precise Drop Height Adjustment: The height of the drop is easily adjusted using a nut on the cup carriage, with verification provided by the included plastic Casagrande grooving tool and gauge.
• Effortless Operation: A simple on-off switch controls the motor, automating the test process for optimal efficiency and accuracy.
• Easy Maintenance: The brass cup attaches to the carriage via a pin, allowing for quick removal for cleaning and inspection.
• Durable Construction: All mechanical components are machined from solid brass for long-lasting performance. The unit is mounted on a stable base with rubber feet to isolate it from the work surface and prevent movement during operation.

Compliance and Specifications

This device is engineered to meet the stringent requirements of common soil testing methods, ensuring your results are reliable and compliant.
