● Mirrored stainless steel liner for easy cleaning in the studio.
● Natural convection circulation mode is adopted, which is noiseless and avoids the volatilization of samples during the test.
● The door of the box is equipped with an observation window, which is convenient for observing the experimental process in the box.
● Fuzzy PID controller, accurate temperature control, small fluctuation, with timing function, the maximum time setting value is 99 hours and 59 minutes.
● Independent temperature limit alarm system, automatic interruption when the limit temperature is exceeded, to ensure the safe operation of the experiment without accidents. (Matching)

◆ LCD multi-segment programmable controller (Matching)
● Multi-segment LCD programmable controller, one-screen display of various parameters, menu-based operation interface, can simplify the complex test process, and truly realize automatic control and operation.
● Multi-stage temperature, time and heating rate can be set and programmed at the same time, and the gradient control of temperature rise can be carried out, and the functions such as slow heating up from the initial temperature in the box can also be preset, and the functions of automatic start-up, standby and shutdown can also be preset.
● 7 groups of 63-step programmable programs can be preset, each group has 9 steps, and the setting time of each group is 0~5999 minutes.
◆ Safety features
● Independent temperature limit alarm system, and sound and light alarm to prompt the operator, to ensure safe operation without accidents. (Matching)
● High or low temperature and over-temperature alarm.
◆ Ultraviolet sterilization system (Matching)
● The inside of the chamber can be disinfected regularly, which can effectively kill the floating bacteria in the circulating air in the chamber, so as to effectively prevent pollution during cell culture.
