The Potentiometer Apparatus is a microcontroller-based titrator designed for precise aqueous, non-aqueous, and red-ox titrations. It features a built-in magnetic stirrer and a valveless dispenser that allows quick and easy switching between different titrants. The system supports single, double, and multi-peak titrations, with the ability to detect up to 10 peaks for advanced analysis. A large graphical display ensures clear visibility of results, while up to 100 test methods can be stored for efficient workflow. The built-in RS-232 interface enables seamless data transfer to a PC, making it ideal for laboratory and quality-control environments.
