I. Overview

YUC.HTZXB4-1 intelligent four-joint fine-grained soil change head permeability instrument is a kind of indoor geotechnical test instrument to measure the permeability coefficient of soil. Because of its small permeability coefficient, it usually takes several hours or several hours to complete a test.

This instrument is designed intelligently on the basis of satisfying the penetration principle of Darcy's law, and improves and improves the construction of the instrument. It can also greatly liberate labor productivity by using computer to collect data and process automatically, without manual reading, reduce human error, improve work efficiency and test accuracy, and greatly liberate labor productivity.

II. Main technical indicators
