Milwaukee MI456 PRO Mini Titrator for Titratable Acidity in Wine

The Milwaukee MI456 PRO Mini-Titrator makes the measurement of Total Titratable Acidity simple.  It uses a neutralization reaction - the reaction between the acids found in wine and a base. This type of reaction forms the basis of titration methods of analyzing acids.

The MI456 automatically dispenses the titrant, determines the endpoint, and completes the calculations in a fraction of the time needed for a manual titration. It uses a pre-programmed method and lab grade pH electrode, combined with an algorithm, to determine the end of the titration reaction.

It is accurate to ±5% of the reading with a resolution of 0.1 g/L and a range of 0.0 to 25.0 g/L of tartaric acid.  The titrator uses a piston-driven pump for accurate dynamic dosing, a built-in magnetic stirrer for a faster reaction, and lab grade pH electrode.

Features:

• Fast, easy-to-read results 
• Accuracy to ±5% of reading
• Easy measurement: just measure the wine sample, add the reagents as directed, prepare pH probe and pump, add the stabilizer, and start the titration by pressing the start button
• Refillable, double junction lab grade pH electrode for fast results with a screw on cap to ensure proper storage
• Automatic temperature compensation from 0.0 to 100.0 C with temperature probe included
• 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
