■ Common characteristic
● Classical mode of heat transfer and uniform temperature.
● Double layers of reinforced glass observation window is convenient to observe the experiment status at any time.
● Special function key for temperature setting.
● Auxiliary menu makes over-temperature alarm, deviation calibration, and menu buttons lock come true.
