Milwaukee MI456US PRO Mini Titrator for Titratable Acidity in Wine

Lab Grade. Accurate. Simple. Automated.

The Milwaukee MI456US PRO TA Mini-Titrator is preferred by wine makers seeking results faster with lower costs and simple operation. The instrument comes with a preprogrammed analysis method designed for Total Titratable Acidity measurements on wine. The MI456US uses a piston-driven pump for accurate dynamic dosing, a built-in magnetic stirrer for a faster reaction and lab grade pH electrode. The MI456US automatically dispenses the titrant, determines the endpoint, and completes the calculations in a fraction of the time needed for a manual titration. The MI456US uses a preprogrammed method and lab grade pH electrode combined with an algorithm to determine the end of the titration reaction.

Summary

The Milwaukee MI456 PRO TA Mini Titrator is preferred by wine makers seeking results faster with lower costs and simple operation.

The Milwaukee PRO TA Mini Titrator offers:

Accuracy

The MI456 PRO Mini Titrator is accurate to 5% of the reading with a resolution of 0.1 g/L with a range of 0.0 to 25.0 g/L of tartaric acid. The titrator uses piston-driven pump for accurate dynamic dosing, a built-in magnetic stirrer for a faster reaction and lab grade pH electrode.

Simplicity

The MI456 PRO Mini-Titrator is designed to for simple one button operation with pre-standardized titrant and pre-measured reagents for easy set up.

Automated operation

The MI456 PRO Mini-Titrator uses a precision piston style dosing pump that dynamically adjusts the dosing volume as the voltage changes. With the MI456 PRO Mini-Titrator, you get a faster result with no need for manual intervention or calculation.

Design features

• 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
• Automatic temperature compensation
• 700 rpm built-in stirrer
• Simple and reliable peristaltic pump that ensure high dosing repeatability
• Compact 8.2 x 8.4” footprint
• Built-in algorithm to analyze the shape of the electrode response and to determine the reaction completion that automatically completes the analysis, makes all necessary calculations and assures a user friendly interface

Cleaning and Storage

All pH sensors have a limited life and response time gets longer with age. Properly maintaining your pH electrode will give you fast, accurate results for longer. So, be sure to order the Milwaukee Maintenance Kit code PH-Main at checkout time!  This will be needed to help clean and condition the pH electrode before use!

Storage

To minimize clogging the pH probe needs to be kept hydrated. Long periods of dry storage will damage the sensitivity of the probe. Allowing the probe to dry out may also result in the junction hole getting clogged.

Storing in pH probe storage solution MA9015 or pH calibration buffers will help address both these issues. Do not store in tap water or DI water. This will damage the sensitivity of the probe.

The best way to store the probe is with the probe's cap filled with storage solution or calibration buffer and the cap tightened to prevent leakage. It is also recommended that to store the electrode upright to further reduce the potential for leakage.

Calibration

The pH sensing bulbs become less sensitive over time so make sure that you are calibrating regularly to keep your MI456 Mini-Titrator readings accurate. Also, calibrate after cleaning or a long period of storage.
