Automatic Potentiometric Titrator NAPT-104

Automatic Potentiometric Titrator NAPT-104 is compact, automated titration device to determine the concentration of the target substance in solution by reacting it with a measured amount of another chemical. It performs simple routine laboratory titrations and eliminates any kind of manual error. Adopting a modular design, it is easy to operate with quick results and high precision and accuracy.
