Milwaukee Instruments, MI455US, PRO Mini Titrator for Sulphur Dioxide in WineThe Milwaukee MI455 PRO Mini-Titrator makes the measurement of free and total Sulphur 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.Features:Fast, easy to read results Accuracy to +/-5% of readingEasy 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 buttonRefillable, double junction lab grade ORP electrode for fast results with a screw on cap to ensure proper storageCompact design with a footprint of just 8.2 x 8.4 inchesBuilt-in stirrer is automatically maintained at a speed of 1500 rpmBuilt-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 userSimple and reliable peristaltic pump that ensure high dosing repeatability with the ability to calibrate with the provided Milwaukee standardsAbility to easily measure both free and total SO2.
