●Mirror stainless steel liner, easy to clean the studio.
● It adopts natural convection circulation mode, no noise, and avoids volatilization of samples during the test.
● There is an observation window on the door of the chamber, which is convenient for observing the experiment process inside the chamber.
● Fuzzy PID controller, accurate temperature control with little fluctuation, with timing function, the maximum time setting value is 99 hours and 59 minutes.
● Independent temperature limit alarm system, which will be automatically interrupted when the temperature exceeds the limit, ensuring the safe operation of the experiment without accidents. ( optional )

◆LCD multi-segment programmable controller ( optional )
● Multi-segment LCD programmable controller, one-screen display of various parameters, and menu-style operation interface can simplify the complicated test process and truly realize automatic control and operation.
● Parameters such as multi-stage temperature, time and heating rate can be set and programmed at the same time. It can control the gradient of temperature rise, slowly rise from the initial temperature in the box, and can also preset functions such as automatic startup, standby and shutdown.
● 7 groups of 63 steps can be preset, each group has 9 steps, and each group can set the time from 0 to 5999 minutes.
◆Security function
● Independent temperature limit alarm system, and sound and light alarm to remind the operator to ensure safe operation without accidents. ( optional )
● High or low temperature and over-temperature alarm.
◆ Ultraviolet sterilization system ( optional )
● It can regularly disinfect the inside of the box, which can effectively kill the floating bacteria in the circulating air in the box, so as to effectively prevent the pollution during cell culture.
