Titrators are specialized instruments that perform titrations with minimal operator intervention and can thus minimize errors, improve throughput, and facilitate documentation. There are two major titrator types: potentiometric acid-based designs and Karl Fischer titrators.

Top 6 Questions You Should Ask When Buying a Titrator

1. How precise is the titrant delivery system?

a. Is the titrant delivery system certified for accuracy?

2. Can additional titrants be used without having to purge burettes?

3. What information is included in the titrator’s display and reports?

4. Is the titrator limited to proprietary electrodes?

a. What is the replacement cost for electrodes?

5. Is the software field upgradeable?

6. What is the service and repair policy?

a. Is on-site support offered?
b. If something goes wrong with the meter, can it be fixed locally?
c. What is the general turnaround time for repair?
