Milwaukee MI455 PRO Mini Titrator for Sulphur Dioxide in Wine

The Milwaukee MI455 PRO Mini-Titrator makes the measurement of free and total Sulphur Dioxide simple. It can be used to test for free and total SO₂ in all wines. Using a modified Ripper method, it doesn’t rely on colour change but instead uses potentiometric detection.

The MI455 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 specialized ORP 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 1 ppm with a range of 0-400 ppm. The titrator uses piston-driven pump for accurate dynamic dosing, a built-in magnetic stirrer for a faster reaction, and lab grade platinum-ringed ORP electrode. It is designed to for simple one button operation with pre-standardized titrant and pre-measured reagents for easy set up.

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 with a screw on cap to ensure proper storage
Compact design with a footprint of 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 ensures a simple and effective interface for the user
Simple and reliable peristaltic pump that provides high dosing repeatability as well as the ability to calibrate with the provided Milwaukee standards
Ability to easily measure both free and total SO2
