170-0455 - Free & Total Sulphur Dioxide Mini-Titrator

The Milwaukee 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, including red. Using a modified Ripper method, the titrator does not rely on color change but uses potentiometric detection. The titrator 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. DESIGN 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 for fast results with a screw on cap to ensure proper storage 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 Ability to easily measure both free and total SO2 SPECIFICATIONS Range: 0 to 400 ppm SO2 Resolution: 1 ppm Accuracy: 5% of reading Method: Ripper titrimetric method Principle: Equivalence point redox titration Sample volume: 50 mL ORP Electrode: MA924B/1 (included) Pump pressure: 0.5 mL/min Stirring speed: 1500 rpm Environment: 0 to 50 °C (32 to 122 °F) ; max 95% RH non-condensing Power supply: 220V/50Hz; 10VA Dimensions: 8.2 x 8.4 x 6.4 inches (with beaker) Weight: 77.6 ounce
