Problems solved by technology

[0002] In chemical experiments, reagent burettes are commonly used instruments, but ordinary burettes have very high requirements for operation and use, and you need to pay attention to experimental changes at any time to determine the amount and time of titration, which is relatively troublesome. If you can change In this case, designing a titration device that can automatically titrate and control the titration will bring convenience to future experiments and work.
