The supporting software set consists of Mixer -- mixer test and control software, Plastic -- extruder test and control software, WinNian -- apparent viscosity test data processing software. Mixer and Plastic software interface has rich functions, which can complete the measurement, setting and control of rotating speed, torque, temperature and pressure, and the curve window can display the curve of the above data versus the time in real time.These data can be processed and mapped by software, test and control software to form an test report, and output by color printer. It also has the functions of multiple curve superposition and smooth curve processing.

ZJL-200 torque rheometer is an automatic test instrument with computer as the core. Data acquisition, control and test data processing are completed by the relevant software.

This not only shows that the instrument is easy to operate, the control is accurate, the experimental data processing and the result output are fast and efficient。More importantly, with the support of the software, it can complete the functions that the traditional torque rheometer cannot complete.For example, linear acceleration measures the shear-sensitive properties of a material.Calibration of  the die during the measurement of the relationship between apparent viscosity and shear rate of materials.The design idea of ZJL-200 torque rheometer is to achieve function expansion and performance improvement through software development on the basis of minimizing the increase of hardware equipment, so it has a high cost performance.
