A titrator is a device that can perform various titrations automatically, mainly used to quantitatively analyze the target substance in the sample. ‌Titration is to determine the concentration of the sample to be measured by slowly adding a standard solution of known concentration to a sample of unknown concentration, measuring the volume required to complete the reaction. The titrator can automatically perform all operations from dropping solution, determining endpoints to calculating concentrations, and is widely used in product quality control, analysis and testing fields. ‌‌
