Load resolution: ±180000 step;

Displacement resolution: ±180000 steps;

EEPROM can be adjusted by PC and data memory

The sample has a diameter of 300 mm and a height of 600 mm

The inner frame facilitates sample preparation

Equipped with guide bushing

The chassis and top cover are equipped with two outlets for measuring pore pressure or pore pressure

Fully automatic, pneumatic servo control system to generate air pressure or hydrostatic pressure

Closed-loop control of constant pressure/stress or pressure/stress step by step loading

It can be controlled by the menu command through the computer or directly through the integrated touch panel

Can be used for penetration test, triaxial shear, pneumatic consolidation

Pressure range: 1MPa (optional 1.6MPa)

Pressure resolution: 0.1KPa

Power supply voltage 220V

Maximum pressure: 1MPa Output: 0-10V

The automatic volume measurement system is used to measure small volume changes during the triaxial test, completely independent of temperature and pressure changes. It overcomes the measurement errors caused by temperature, pressure and friction in other measurement systems using displacement sensors.
