Titrator

A titrator quantitatively adds a reagent of known concentration to react with the substance being tested, and calculates the content based on the volume consumed. It is used for chemical analyses such as acid-base neutralization and redox reactions, and is applied in chemical engineering and environmental protection fields to detect component concentrations.
Selection
When selecting, consider the measurement accuracy and match the sample characteristics to the burette capacity, align the reaction type with the potentiometric or colorimetric determination method, evaluate operational convenience based on the level of automation, and pay attention to electrode and reagent compatibility for maintenance.
