1.The inner tank is made of high-quality stainless steel, which has the characteristics of corrosion resistance, acid resistance, easy cleaning, and no rust. 2.Microcomputer intelligent temperature controller, P.I.D. control, stable temperature control, high precision, LED high brightness digital display, intuitive and clear. With overtemperature audible and visual alarm function, the temperature setting value of overtemperature alarm can be adjusted. When the temperature value in the incubator exceeds the setting value by 0.5 ℃, the alarm will be given and the heating circuit will be cut off. 3.Double-layer door structure: After the outer door is opened, observe the laboratory experiment through the inner door made of high-strength tempered glass, and the temperature and humidity will not be affected. 4.The CO2 concentration sensor adopts the infrared probe imported from Finland, which can directly display the CO2 concentration in the box, and the operation is reliable. 5.The independent door heating system can effectively avoid condensation on the inner door glass and prevent the possibility of microbial contamination due to condensation on the glass inner door. 6.Water pan is used for natural evaporation and humidification in the studio, and the humidity is directly displayed by the instrument. 7.The box is equipped with an ultraviolet germicidal lamp, which can periodically sterilize the culture room with ultraviolet rays, so as to more effectively prevent cell contamination during the culture period. 8.The independent temperature limit alarm system automatically interrupts when the temperature exceeds the limit to ensure the smooth progress of the experiment (optional). 9. The CO2 inlet is equipped with a high-efficiency microbial filter, which can effectively filter more than 3 diameters μ M particles, the filtration efficiency reaches 99.99%, effectively filtering bacteria and dust particles in CO2 gas (optional).
