I. Overview

GYS-2 (LP-100D) digital display liquid-plastic limit joint tester is used to determine the liquid limit and plastic limit of soil. It provides reliable data for classifying soil types, calculating natural consistency and plasticity index, and can be used for engineering design and construction of roads, railways, water conservancy and electricity, metallurgy, construction and other departments. The instrument uses digital display and other technologies to automatically time, measure and display. It has the characteristics of stable performance, reliable data, measurement precision, intuitive and clear reading, simple and convenient operation, and high work efficiency. It has been included in the standard highway geotechnical test specification of the Ministry of Communications, and is one of the necessary instruments for geotechnical testing.

2. Main use

It is used to jointly determine the liquid limit and plastic limit of cohesive soil <0.5mm, that is, when the cohesive soil is in a plastic state, the maximum water content and the minimum water content, in order to classify soil types, calculate natural consistency and plasticity index, and provide parameters for engineering. use. The instrument adopts digital technology and digital display displacement sensor; the cone meter freely falls into the soil sample, electromagnetic manual, automatic control of cone suction and release, automatic timing for 5 seconds, buzzer when it arrives, etc. It is easy to use, simple to operate, and easy to unify. , the readings are accurate and intuitive, and there is no other additional force influence.
