Automatic Titrator COM-A19

Automatic Titrator with flexibility for you.

Automatic titrators use high-accuracy electrically-actuated burettes and end point detection based on electrochemical sensors, thus enabling high-accuracy measurements with no human errors.
Automatic Titrator COM-A19 faithfully retains the functionality of its popular predecessor model while adding new features to address the needs of users.

*Since sales availability, products and services vary by country and region, please contact your Hitachi High-Tech Science contact, the exclusive distributor, for specific requests and questions.
