Ⅴ 、Main function features：

This instrument has a beautiful appearance and adopts advanced electronic modular design to ensure stable product quality. The computer tracks data acquisition and data processing in real time. Multiple color curves (see the following page) depict the change process of the  sample. The test process is completely automated, programmed, and humanized.

The test stand and oil tank of this equipment are all made of stainless steel, with small expansion coefficient and high mechanical precision;；

This product has sound and light alarm function, which will give sound and light alarm prompts at each stage of the test and after the test.；

This product has the features of automatic lifting and lowering of the test frame and automatic loading of weights, which is easy to operate and saves time; the heat-averaging system is hidden inside the machine, and the heat-averaging stirring speed is adjustable;

After the test, the instrument can be cooled with tap water, or with a water tank for self-circulation cooling (the instrument is equipped with a circulating pump), or with an external cooling machine for rapid cooling; (the manufacturer can provide the cooling machine, the price is negotiable)

You can also compare the authenticity of the data on the display with the independent digital display device on this instrument, which is more convenient for measurement department to correct the accuracy of the instrument.

The  software  has  the   function  of  storing  and  retrieving   sub   item  data,  as  well  printing  Word reports.Using our company's unique computer program control uniform temperature system.Our company is the first to use this technology in China. The program control uniform temperature heating system for PTC test was successfully manufactured for Zhejiang University. When the deformation of the test is reached, the test is automatically stopped and the temperature value is flashed，to achieve the purpose of prompting.After the test is completed, the software can automatically store and print the test results according to the user's settings, and the graphical display function can display the real-time:temperature - time and deformation - time curve, temperature - deformation curve.

During the test ， in order to prevent  excessive  oil  or oil with  a  large  expansion  coefficient  from expanding and overflowing due to heat,an overflow oil recovery device is specially installed; it has upper limit temperature protection and oil fume exhaust functions; and is easy to operate.
