Technical features: 1. Full-color large-screen LCD screen display and screen touch mode operation; 2. Pre-set four fixed programs (parcels, solutions, instruments, tests) and leave two custom spaces for the user to personalize the set of working procedures; 3. Microcomputer modular design of the control system, water tank and sterilization chamber dual PID temperature control; 4. Configure the key parameters of the micro printer's print sterilization process; 5. Double pressure double temperature digital dynamic display and pressure gauge display; 6. The screen uses man-machine dialogue and prompting methods to effectively avoid the occurrence of erroneous operations. 7. The door is opened and locked as an electric method, the control is flexible and reliable; 8. The sterilizer is designed with its own steam generator and jacket structure; 9. The sterilization chamber and the jacket are respectively equipped with overvoltage protection devices; 10. The jacket and the sterilization chamber have over-temperature alarm control respectively, and stop the sterilization process after the alarm; 11. Sterilization conditions (preheating temperature of the jacket, locking the door, sealing, etc.) are not met and cannot enter the sterilization process; 12. The sterilizer has a safe exit procedure, which interrupts the sterilization procedure for some reason. After confirming the exit, the system automatically terminates the sterilization according to the “safe exit” method. 13. The sterilizer will suffer from a lack of water during its working process, and it can automatically cut off the heating power supply and realize replenishment. The replenishment will continue to work; 14. After the sterilization work is over, the alarm and the screen will prompt at the same time when the temperature and pressure reach the opening conditions; 15. Integrated water ring vacuum pump, low noise and vacuum can reach -0.095MPa below; 16. The maximum sterilization temperature can reach 135 °C.
