Mi455 PRO Mini Titrator for Sulfur Dioxide in Wine

The Milwaukee Mi455 PRO Mini-Titrator makes the measurement of free and total Sulfur Dioxide simple. The Mi455 PRO can be used to test for free and total SO₂ in all wines, including red. Using a modified Ripper method, the Mi455 PRO Mini-Titrator does not rely on color change but uses potentiometric detection. The Mi455 PRO Mini-Titrator automatically dispenses the titrant, determines the endpoint, and completes the calculations in a fraction of the time needed for a manual titration. The Mi455 PRO uses a preprogrammed method and specialized ORP electrode combined with an algorithm to determine the end of the titration reaction.

DESIGN FEATURES:

• Fast, easy to read results 
• Accuracy to ±5% of reading
• Easy measurement: just measure the wine sample, add the reagents as directed, prepare ORP probe and pump, add the stabilizer and start the titration by pressing the start button
• Refillable, double junction lab grade ORP electrode for fast results with a screw on cap to ensure proper storage
• Compact design with a footprint of just 8.2 x 8.4 inches
• Built-in stirrer is automatically maintained at a speed of 1500 rpm
• Built-in algorithm to analyze the shape of the electrode response and to determine the reaction completion that automatically completes the analysis, makes all the necessary calculations and assures a simple and effective interface for the user
• Simple and reliable peristaltic pump that ensure high dosing repeatability with the ability to calibrate with the provided Milwaukee standards
• Ability to easily measure both free and total SO₂
