Appointment sintering		Optimize equipment utilization, ensure sintering process stability, save waiting time, and achieve efficient and orderly sample preparation.
Nonlinear temperature correction		By using algorithms to nonlinearly correct the temperature deviation between the control point and the sample due to their different positions in the temperature field, the consistency between the control temperature and the sample temperature is improved, the operation is simplified, and the accuracy of experimental data is enhanced.
remote control		You can log in to the control system anytime and anywhere through computers, mobile phones, and other terminals to view the operating status of the heating furnace (temperature, pressure, heating rate, etc.), and remotely adjust parameters and start/pause programs according to experimental needs. No need to travel back and forth to the laboratory at night or on holidays to meet the parameter tuning needs during the experimental process; Real time monitoring of key experimental processes can also be achieved during cross regional business trips, significantly reducing ineffective commuting time and allowing researchers to allocate work energy more efficiently.
