While titration is a basic analytical method, titrators are specialized instruments that perform titrations with minimal operator intervention. They 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
- How precise is the titrant delivery system? Is the titrant delivery system certified for accuracy?
- Can additional titrants be used without having to purge burettes?
- What information is included in the titrator’s display and reports?
- Is the titrator limited to proprietary electrodes? What is the replacement cost for electrodes?
- Is the software field upgradeable?
What is the service and repair policy?
- Is on-site support offered?
- If something goes wrong with the meter, can it be fixed locally?
- What is the general turnaround time for repair?
