Ⅲ 、System composition：

The  system  structure  design  adopts  the  "E  "word  frame  streamline  design  to  ensure  the  structural strength.The overall appearance design is beautiful and generous; Strong sense of technology. The weight loading  mechanism  brand  precision  ball   screw  to  complete  the  mobile  loading  and  transmission  of weights.The selection of weights is controlled by a program-controlled synchronous motor, which drives the bidirectional threaded  screw  pair  to  select  the  weights  of the  required mass  according  to the  standard requirements; the overall loading process does not require manual operation, all programs are automatically loaded, which saves the time and effort of manual loading, making the test simpler, the operation more convenient, the data more accurate, and the performance more stable.The heating unit adopts spiral heating wire for overall heating, and is controlled by thyristor pulse regulation. The overall temperature of the barrel is uniform, with high temperature control accuracy. The furnace body can be moved out as a whole, which is more convenient to the cleaning of the remaining materials and the furnace after the experiment. High-tech measurement and control system, the software interface is simple and intuitive, you can set the test mode, and related operating parameters, real-time display of relevant parameters and calculation results.

Ⅳ 、Accuracy level：Level 1
