Automatic titration systems.
In short: Sonnen titration systems combine 16-bit tri-primary color sensors with potentiometric inputs, covering acid–base, redox, precipitation, complexometric and non-aqueous titration. Dedicated models serve chloride ion (T10), fatty acid value & acid value (T12), COD and total organic material (T13), and multifunctional titration (T03, T11).

Intelligent multi-function titrators with 16-bit tri-primary color sensors and potentiometric inputs — acid–base, redox, precipitation, complexometric and non-aqueous titration, plus dedicated models for chloride ion, fatty acid value & acid value, and COD.

Frequently asked questions.
Which titration methods are supported?
Acid–base, redox, precipitation, complexometric and non-aqueous titration. Detection is by 16-bit tri-primary color sensor and/or potentiometric input depending on model and configuration.
Which model for chloride / fatty acid value / COD?
T10 is the dedicated chloride-ion titrator, T12 covers fatty acid value and acid value, and T13 covers COD / total organic material. For mixed workloads, the T11 multifunctional titrator is the general choice.
