Characteristics:
▲ The shell is made of high quality steel, the surface electrostatic spraying process, the film is firm and beautiful, beautiful shape, and novel.
▲ The outer is with observation window,which can observe the heating of the material at any time.
▲The temperature control system adpots microcomputer single-chip technology, intelligent digital display meter,with PID regulation characteristics, setting time, modified temperature difference, over-temperature alarm and other functions, high precision temperature control, strong function.
▲Professionally designed airflow circulation system let the heat generated by the bottom of the heater goes into the working room by the way of natural convection, thereby improving the temperature uniformity in the working room.
▲It adpots new synthetic silicone seal strips,can operate long time at high temperature, long life and easy replacement.
▲ can adjust the inlet air and exhaust size of the working room.
▲ the height of the shelf and shelf number can be adjustable with the user's requirements.
▲We can also add printer and RS-485/232 interfaces before the order according to user requirements. 485 interface: 800 RMB; printer: 2800 RMB;
