Four-Station Fully Automatic Pneumatic Consolidation Apparatus (Medium and Low Pressure)

Description

Product Introduction

The SL‑4 fully automatic pneumatic consolidation apparatus is used to determine the compressibility of soils under various loads and with lateral confinement. The complete system comprises a consolidometer, a pneumatic pressure controller, a multiplex communication converter, and a data acquisition system. It can perform both conventional slow‑consolidation tests and rapid consolidation tests, enabling the determination of pre‑consolidation pressure and the consolidation coefficient. The system features stable and reliable pneumatic pressure control, low noise, independent control of consolidation pressures, user‑friendly software installation, compact dimensions, and an intuitive software interface. In particular, the ability to set consolidation pressures independently significantly enhances the instrument’s flexibility, shortens test durations, and delivers excellent value for money.
