Sample holder

The sample holder is made by uni-body process, load rod, pressure head, needle are made of Iron nickel alloy, no any heat expansion under 300 thus guarantees high accurate test data;


Heat medium box

The heat medium box is made of SUS 304, features corrosion & aging resistant, filled with 20mm thick high temperature resistant asbestos for heat insulation, it can greatly reduce the heat loss during heating;

The cooling tube made of 10mm copper tube, features good thermal conductivity, works together with water cooling can reach fast cooling effect;


Electronic control system

Delta PLC with modularized independent electric control system, features stable performance, high accuracy, much lower failure rate


Software control system

The software features functions of test curve drawing, data management, test report print, data analysis;
