Mini titrator for sulfur dioxide Mi455

For the determination of Free and Total Sulphur Dioxide in wine.

The Mi455 is a mini-titrator microprocessor, easy to use, for the determination of sulfur dioxide in the wine, which provides direct readings quickly, precisely and accurately, with a scale from 0 to 400 ppm. The tool uses a pre-programmed method for analysis of free and total sulfur dioxide in wine samples. The sulfite is the most effective and widely used protection agent for wines and for grape against premature oxidation, bacteria and mold, which could alter the wine.
Sulfites maintain the freshness of the wine and help preserve the bright color. Also they impede, for over a year, the deterioration; what it is important for the purpose of aging. It is important to know the amount of sulfur dioxide present in the wine, but especially free sulfur dioxide, ie the active part which guarantees protection.
You can learn about the molecular sulfur dioxide which is the true fraction of sulfur dioxide to be antiseptic.
