Special wine mini-filter for measuring free and total SO2 (with starter kit for 46 tests)
HI84500-02 comes complete with HI3148B redox electrode, HI7082 electrolyte solution (30 mL), SO2 reagent kit [consisting of : 1 bottle HI84500-50 (230 mL), 1 bottle HI84500-51 (230 mL), 1 bottle HI84500-55 (120 mL), 1 bottle HI84500-60 acid reagent (230 mL), 1 bottle HI84500-61 basic reagent (120 mL), 50 sachets HI84500-62 stabilizer], 2 beakers 100 mL, 2 beakers 20 mL, scissors, 1 HI70500 (tube kit with cap for titrant vial, tip and valve), syringe 5 mL, plastic pipette 1 mL, magnetic bar, 2 sachets of wine stain cleaning solution for electrodes and 12 V adapter.
This model features a high-precision piston dosing system, optimizing measurements, and a compact housing, ensuring a small footprint on the workstation. It also features automatic stirring speed control, a graphical mode for real-time titration curve generation, 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
Highlights:
New: dynamic dosage with precision piston pump
- Volume of increments added adapted to the shape of the titration curve
- Optimized titration time
- High accuracy and repeatability of results
CAL CHECK
- Calibration quality control function. Warns the user of dirty electrodes or contaminated calibration solutions
mV meter
- As well as being an automatic titrator, HI 84500 can also be used as a mV meter.
On-demand storage
- Stores up to 400 measurements (200 for titration and 200 for mV).
Graphical display / Data export
- Graphical mode generates titration curve in real time and saves data for PC use.
Automatic stirring speed control
- Stirring speed maintained at around 600 rpm according to solution viscosity.
GLP (Good Laboratory Practice) function
- HI 84500 features a GLP (Good Laboratory Practice) function, enabling users to consult pump calibration data.
Improved interface
- The user interface has been optimized to make operation of the titrator even more intuitive.
- Context-sensitive help menu
