Sulfur dioxide measurement made easy

This model features a high-precision piston dosing system, optimizing measurements, and a compact housing, ensuring a small footprint at the workstation. It is also equipped with automatic stirring speed control, a graphical mode generating the tritration curve in real time, PC-readable data storage and a Good Laboratory Practice (GLP) function, enabling users to consult pump calibration data.

Why measure sulfur dioxide _SO2?

Antiseptic, effective and antioxidant, it is an indispensable auxiliary for winemakers from the vat to bottling. The total absence of SO₂ is rare. Even in the absence of sulfiting, small doses are formed by fermentation yeast. Its action is multiple: it kills bacteria and germs of wine diseases, protects the aroma and preserves it from too intense oxidation by setting a sufficiently low redox level. EU regulations lay down very precise maximum SO₂ levels for different types of wine:

Dry wines, sugars below 4 g/L

• Reds 160 mg/L (Vins de Pays 25 mg/L)
• Whites and rosés 210 mg/L (Vins de Pays 50 mg/L)

Wines, sugars above 4 g/L

• Red 210 mg/L
• Whites and rosés 260 mg/L
• Derogations for various AOCs to 300 mg/L
• Derogations for AOCs produced with botrytized grapes at 400 mg/L
