Titration systems with precision dosing pumps are available to perform a sulfur-dioxide titration. There are options for titrators with two analog inputs and two dosing pumps. This configuration allows for one channel to be used with a pH electrode and titrant for acid/base titrations and the other channel for a ORP probe and titrant for the titration of sulfur dioxide.
An application specific titrator for wine is available for the measurement of sulfur dioxide. This meter uses pre-standardized titrants and pre-packaged reagents to simplify the measurement. With this system everything is included to measure free or total sulfur dioxide in two ranges.
Electrodes & Probes
The following are ORP electrodes for use when performing the redox titration for sulfur dioxide. In this category is the ORP probe with the Hanna Clogging Prevention System (CPS) technology that prevents clogging of the reference junction by solutions with a high solids content.
Solutions for sulfur-dioxide measurement include fill solutions for ORP electrodes, storage solutions and application specific cleaning solutions for wine stains and deposits.
In this category are the replacement titrants and reagents used with the minitirators. Also included in this category are titrants and reagents for sulfur dioxide that can be used with most potentiometric titration systems.
Accessories for sulfur dioxide titration include spares for the minititrators. The spares include the replacement tubing set and valve, plastic beakers, and magnetic stir bars used for mixing.
