An automatic titrator (also called automatic titration system or titration analyzer) is a laboratory instrument that automates the process of titration. Titration is a quantitative analytical technique where a reagent of known concentration (the titrant) is gradually added to a solution containing an unknown concentration of some species (the analyte) until the reaction is complete (endpoint). The endpoint might be determined by a change in color, pH, potential (mV), conductivity, or other measurable property. Automatic titrators do this process with minimal user intervention, ensuring higher precision, repeatability, and throughput.
