Self-calibration titration device and method

The invention relates to the technical field of titration analysis, in particular to a self-calibration titration device, which solves the problem of hanging drops and the problem of corrosion of the titration device by arranging a super-hydrophobic self-repairing anti-corrosion coating on the inner wall of a titration probe. And self-calibration of the titration device can be carried out. The invention further provides a self-calibration method of the self-calibration titration device, the titration precision and the instrument detection precision in a complex titration environment can be effectively improved, and meanwhile, maintenance-free and remote self-calibration of the titration instrument are realized. The method comprises the following steps: firstly, obtaining a nonlinear compensation table of a titrating solution through an experiment preset stage by utilizing a relationship between titration time and titration volume; and in the online use stage, the pulse of the metering driving mechanism is rec
