The Milwaukee Meters Mi455 Free & Total SO2 mini titrators are available from Pacific Sensor Technologies .
Designed specifically for measuring free and total sulphur dioxide in the winemaking process, the new Mi455 Free & Total SO2 mini titrators from Milwaukee Meters are user-friendly microprocessor-based instruments that provide direct readings in a range of 0 to 400 ppm.
The mini titrators come with a pre-programmed analysis method for free and total sulphur dioxide measurements on wine samples.
Sulphite, a salt or ester of sulphurous acid, but more commonly, sulphur dioxide (SO2), is one of the most effective preservatives used in winemaking.
Key advantages of Sulphite as a preservative:
- Preserves by safeguarding musts and wines against premature oxidation and microscopic life forms that could otherwise spoil wine
- Preserves a wine's freshness and helps maintain its colour
- Essential for aging wines beyond their first year to prevent deterioration
- Inhibits wild yeasts, thereby allowing cultured wine yeasts to dominate the fermentation
Sulphites may be ‘bound’ or ‘free’. Bound SO2 combines with aldehyde compounds responsible for oxidation in wines.
Free SO2 results from dissipated active SO2 and is the only SO2 that provides antiseptic and oxidative protection to wines. The effectiveness of free SO2 is dependent on the pH of the media to which it is added.
Milwaukee Meters offers a comprehensive range of affordable water quality instruments that provide superior quality and performance.
