Features
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;
Safety protection
Mechanical limit upper limit protection switch and software upper limit protection, automatic stop after test, admin password
High accuracy measure & control system
High performance temperature and displacement sensor, PID algorithm.
