Robust Construction for Reliable Results

With a high-grade brass cup and a durable hard rubber base, the Liquid Limit Device is specially designed to provide long-lasting performance even in demanding laboratory environments. Its powder-coated finish adds an extra layer of corrosion resistance, ensuring that the equipment remains in excellent condition through extensive use. This reliability is vital for accurate soil consistency and Atterberg limits testing.

Versatile Operation: Manual and Motorised

The Liquid Limit Device is available in both hand-operated and semi-automatic motorised versions, catering to different laboratory requirements. The manual system allows for variable test speeds, while the electric motorised option provides a fixed, standard-compliant drop rate, ensuring consistency and ease of use. A mechanical tally counter guarantees instant and precise measurement of drops during every test.

Compact Design, Easy Setup

Designed for bench-top mounting, this device efficiently utilizes laboratory space with a base size of 120 x 120 mm and a maximum height of 70 mm. The equipments box-packed configuration and straightforward interface make setup and handling simple for users, enhancing workflow efficiency in busy labs. Every key component, including the grooving tool, is included for immediate use.

FAQs of Liquid Limit Device:

Q: How is the Liquid Limit Device used for soil consistency testing?

A: The device is used to determine the liquid limit of a soil sample. A small amount of soil (approx. 100g) is placed in the brass cup, and a groove is made using the included Casagrande tool. The cup is then repeatedly dropped from a standard height of 10 mm until the two halves of the soil come together for a specified distance, counting the number of drops with the mechanical counter.

Q: What are the key benefits of using this Liquid Limit Device?

A: This device offers accurate and repeatable measurements complying with IS:2720 standards, thanks to its corrosion-resistant brass cup and robust construction. Both hand operated and motorised versions are available, providing flexibility, while the mechanical tally counter ensures precise drop counting. Its compact, easy-to-set-up design is ideal for all laboratory environments.

Q: When should I use the motorised function instead of manual operation?

A: The motorised version is recommended when conducting multiple tests requiring consistent drop rates or when operator fatigue is a concern. It provides a fixed, standard-compliant speed, improving repeatability and efficiency, particularly in high-throughput or research laboratory settings.

Q: Where can the Liquid Limit Device be used?

A: This equipment is suitable for use in geotechnical laboratories, educational institutes, construction quality control departments, and civil engineering research organizations throughout India and abroadanywhere Atterberg limits or soil consistency assessments are required.

Q: What is included in the box-packed Liquid Limit Device?

A: The device is shipped complete with a corrosion-resistant brass cup, a hard rubber base, a mechanical tally counter, a standard Casagrande grooving tool, and all mounting accessories. The equipment arrives securely packaged and ready for immediate use.

Q: How often do I need to calibrate or maintain the device?

A: Routine checks should be performed before each use to ensure the cup, base, and drop height mechanism are clean and functioning correctly. Calibration is essential if there is any noticeable deviation in drop height or mechanical counter performance to maintain accuracy as per IS:2720.

Q: What distinguishes this device from other soil testing equipment?

A: Its dual operation modes (manual and motorised), corrosion-resistant brass cup, and adherence to IS:2720 standards set this device apart. The inclusion of a mechanical tally counter with instant response and a full grooving tool make it a complete solution for Atterberg limit testing requirements.
