Burettes and sensors are automatically identified when attached. Errors can be avoided by removing additional data entry steps, thus reducing instrument installation time.


Predefined methods

Over 20 enhanced analytical approaches and calculations from typical application areas come preset in the compact titrators. It is possible to use them directly or easily edit them to match specific requirements.


Secure operation

Users can designate “Expert” and “Routine” user groups to permit full or limited access to techniques, instrument setup parameters, and results.


Simple automation

Compact titrators are designed to support an automatic Rondolino sample changer. It is possible to carry out analysis of up to nine samples. Automated cleaning and conditioning functions help to accelerate daily tasks.


Safe chemical handling

User contact with chemicals can be reduced by automatically draining and refilling the titrator cell and avoiding the overflow of waste with exclusive accessories.
