Titration systems are available to measure Yeast Assimilable Nitrogen (YAN). These systems include a mini-titrator designed specifically for measuring formol nitrogen in wine. Potentiometric titration systems can measure a wide range of parameters are available; including one that has wine parameters pre-programmed into the meter. The potentiometric titrations systems have a precision dosing pump for precise dosing of a titrant. These systems use a pH probe determine the endpoint.
