Precision dispensing device with automatic titration function powered by electric motor. Equipment that automates quantitative analysis including acid-base titration, redox titration, and complexometric titration for quality control and analytical operations in manufacturing industries. Unlike manual burettes, enables continuous dropping at constant speed, endpoint detection, and data recording through electric control. Used for raw material analysis in chemical plants, content testing in pharmaceutical factories, and quality inspection in food factories. High-precision analytical instrument equipped with digital display, program control, and RS-232C communication functions. Standard specifications include capacity range of 10-50mL and accuracy of ±0.1% or better.
