Potentiometric Titrator LZ-PTM-A102 is a modular electrochemical analyzer that finds a titration endpoint by tracking potential change. It combines a burette unit with PTFE tubing and a rotary valve, a control unit and a measuring unit with a pH composite electrode and magnetic stirring. It offers 0.20% repeatability and a 10 mL standard burette, and stores results for review. Labs use it for acid-base, redox, precipitation and complexation titrations in food, drug, water and chemical testing.
