Matrix Multi‑Field Coupled Adsorption Test System HC-HTMC

System Description

This system is designed for measuring and observing the matric suction and drainage characteristics of contaminated soil under high-temperature environments. It simultaneously enables analysis of drainage hysteresis in ceramic plates as well as condensation effects within the chamber. The pressure chamber features a top-mounted visualization design, allowing for the observation and recording of the entire sample process through image measurement technology.

Basic Parameters

• Specimen size: φ61.8×20mm / φ61.8×40mm.

• Air pressure range: 0~0.5MPa / 0~1.5MPa.

• Temperature: Ambient to 60℃, electric heating accuracy: ±0.5℃.

• Humidity monitoring accuracy in pressure chamber: better than 1%RH with temperature compensation.

• Heating medium: Electric heating.

• Soil sample deformation measurement: Binocular DIC image measurement.

• Balance capacity: 220g, accuracy: 0.001g, equipped with evaporation compensation balance.

• Macro high-density electrical monitoring: 8–16 channels, connected to external equipment via coaxial sealed cable connectors (used to obtain the internal resistance field of rock mass and derive the internal water content distribution). 

System Features

• Spiral channel designed at the bottom of the ceramic plate to allow flushing during testing.

• Hydrophobic coating applied on the inner wall of the pressure chamber to reduce condensation.

• Electrical method-based infiltration front detection with coaxial cable connectors.

• Table surface treated with blackening process.
