The Milwaukee MI455US PRO SO₂ Mini-Titrator is preferred by wine makers seeking results faster with lower costs and simple operation. The MI455US uses a piston-driven pump for accurate dynamic dosing, a built-in magnetic stirrer for a faster reaction and lab grade platinum-ringed ORP electrode. Using a modified Ripper method, this mini-titrator does not rely on color change but uses potentiometric detection. The MI455US automatically dispenses the titrant, determines the endpoint, and completes the calculations in a fraction of the time needed for a manual titration. The MI455US uses a preprogrammed method and specialized ORP electrode combined with an algorithm to determine the end of the titration reaction.
