YKM TEST provides a complete range of specialized laboratory equipment designed for accurate determination of Atterberg Limits and Particle Size Analysis. Our testing instruments are developed to deliver high precision, reliability, and compliance with international standards such as ASTM and BS, making them ideal for geotechnical laboratories, universities, and engineering firms.

The Atterberg Limits are one of the most important parameters in geotechnical engineering. They define the boundaries between the different states of soil consistency — solid, semi-solid, plastic, and liquid. At YKM TEST, our equipment for determining the Liquid Limit, Plastic Limit, and Shrinkage Limit is designed to provide accurate, repeatable results every time.

Our Liquid Limit Device, Casagrande apparatus, and motorized models are built for smooth operation and long-term durability. The Plastic Limit Sets include all the necessary tools for consistent and standardized testing. With these instruments, engineers can easily determine soil plasticity and behavior under varying moisture conditions — data that is critical for assessing foundation stability, settlement, and soil strength.

By using our Atterberg Limits testing equipment, laboratories can classify soils precisely, identify potential swelling or shrinkage issues, and make informed design decisions for construction, roadwork, and embankment projects. In addition to Atterberg testing, YKM TEST offers a complete line of instruments for Particle Size Distribution analysis. This test determines the proportions of various grain sizes in a soil sample, providing insight into the soil’s texture, grading, and drainage properties.

Our sieve shakers, sieves, and hydrometer analysis sets are manufactured with high-quality materials to ensure consistent performance and long service life. Whether you’re analyzing coarse-grained sands or fine silts and clays, our systems produce accurate and reproducible data that comply with global standards.

Proper particle size analysis is essential for understanding how soil will behave under load, how it will retain or drain water, and how suitable it is for specific engineering applications. With YKM TEST equipment, you can conduct these evaluations efficiently and with confidence.
